本申请实施例涉及计算机领域，具体而言，涉及一种消息的传输方法及装置、存储介质及电子装置。The embodiments of the present application relate to the computer field, and in particular, relate to a message transmission method and device, a storage medium, and an electronic device.
背景技术Background technique
目前，对于不同FU（Function Unit，功能单元）之间的通信，通常采用进程间通信的方式，以IPC（Inter-Process Communication，进程间通信）消息作为基本单元。每个IPC消息包含若干个参数，其中内存地址所占的比特数较多。At present, for communication between different FUs (Function Units, functional units), an inter-process communication method is generally adopted, and an IPC (Inter-Process Communication, inter-process communication) message is used as a basic unit. Each IPC message includes several parameters, among which the memory address occupies more bits.
然而，随着NAND（Not AND，是与非，即计算机闪存设备）技术的发展，一个多plane（即，存储矩阵）读写消息需要传递的内存地址的数量越来越多，IPC消息的长度也相应增大，导致读写IPC消息时消耗的资源增加，从而影响了消息的传输效率。However, with the development of NAND (Not AND, that is, computer flash memory device) technology, the number of memory addresses that need to be transmitted for reading and writing messages in a multi-plane (that is, storage matrix) is increasing, and the length of IPC messages is correspondingly increased, resulting in an increase in resources consumed when reading and writing IPC messages, thereby affecting the transmission efficiency of messages.
由此可见，相关技术中的进程间通信消息的传输方法，存在由于需要传输的消息过长导致的消息传输效率低的问题。It can be seen that, the method for transmitting inter-process communication messages in the related art has the problem of low message transmission efficiency due to too long messages to be transmitted.

根据本申请实施例的一个方面，提供了一种消息的传输方法，以由计算机终端来执行本实施例中的消息的传输方法为例，图2是根据本申请实施例的一种消息的传输方法的流程图，如图2所示，该流程包括如下步骤：According to an aspect of the embodiment of the present application, a method for transmitting a message is provided. Taking the computer terminal to execute the method for transmitting a message in this embodiment as an example, FIG. 2 is a flowchart of a method for transmitting a message according to an embodiment of the present application. As shown in FIG. 2 , the process includes the following steps:
步骤S202，获取目标内存地址，其中，目标内存地址为待传输的目标传输消息所传输的、目标缓冲区的缓冲区地址。Step S202, acquiring a target memory address, where the target memory address is a buffer address of a target buffer transmitted by a target transfer message to be transmitted.
本实施例中的消息的传输方法可以应用到同一设备内的不同功能单元FU之间进行通信的场景。对于固件FW（Firmware），不同FU之间的通信主要采用进程间通信方式，通过FU定义不同管道FIFO（First Input First Output，先进先出）。IPC消息作为进程间通信的基本单元，其长度一般以Dword（Double Word，每个word为2个字节的长度，32bit）为单位。每个IPC消息可以包含若干个Dword（比如，16个Dwords），其中包含了消息源、消息目的地、消息唯一标识符、消息类型、消息地址、需要传递的多个buffer（内存地址，读写取数据时用于存放数据）地址等参数。The message transmission method in this embodiment can be applied to a scenario where different functional units FU in the same device communicate with each other. For the firmware FW (Firmware), the communication between different FUs mainly adopts the inter-process communication method, and different pipelines FIFO (First Input First Output, first-in-first-out) are defined through FU. The IPC message is the basic unit of inter-process communication, and its length is generally in units of Dword (Double Word, each word is 2 bytes in length, 32bit). Each IPC message can contain several Dwords (for example, 16 Dwords), which include parameters such as message source, message destination, message unique identifier, message type, message address, and multiple buffers (memory addresses, used to store data when reading and writing data) addresses that need to be transmitted.
在本实施例中，在不同功能单元间进行消息传输之前，可以先获取目标内存地址。这里，目标内存地址可以为待传输的目标传输消息所传输的、目标缓冲区的缓冲区地址，即前述buffer地址。目标传输消息可以是前述IPC消息。In this embodiment, before message transmission between different functional units, the target memory address may be obtained first. Here, the target memory address may be the buffer address of the target buffer transmitted by the target transfer message to be transmitted, that is, the aforementioned buffer address. The target transfer message may be the aforementioned IPC message.
步骤S204，根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值，得到目标标识值。Step S204, according to the base address and the size of the address unit, determine the identification value of the address identification corresponding to the target memory address, and obtain the target identification value.
在IPC消息中，除buffer地址外其他参数较为简单，所占比特（bit）数较少。64位操作系统中一个绝对的buffer地址包含64bit（即，占用2个Dword）。典型的结构体如下，其中，buffer地址占用9个Dwords：In the IPC message, other parameters except the buffer address are relatively simple and occupy a small number of bits. An absolute buffer address in a 64-bit operating system contains 64 bits (that is, occupies 2 Dwords). A typical structure is as follows, where the buffer address occupies 9 Dwords:

不同FU与NCM（Nand Control Manager，闪存控制管理）进程通信最基本的操作有读、写、擦等，其中，读、写的快慢至关重要，决定了产品的基本性能。然而，随着NAND技术的不断发展，一个多plane读写消息需要传递更多个buffer地址，此时，IPC消息长度不得不增大很多。而进程间通信时，IPC消息需要在一个模块写入，并从另一个模块读出，消息长度增大后，读写IPC消息时会消耗较多的CPU（Central Processing Unit，中央处理器）资源。此外，IPC消息在不同FU间传输过程中有时需要多层转发，过长的IPC消息在消息传输时，也会给总线造成很大负担，进而影响传输性能和传输效率。The most basic operations for communication between different FUs and NCM (Nand Control Manager, flash memory control management) processes include reading, writing, and erasing. Among them, the speed of reading and writing is very important, which determines the basic performance of the product. However, with the continuous development of NAND technology, a multi-plane read and write message needs to transmit more buffer addresses. At this time, the length of the IPC message has to be increased a lot. In inter-process communication, IPC messages need to be written in one module and read from another module. After the message length increases, more CPU (Central Processing Unit, central processing unit) resources will be consumed when reading and writing IPC messages. In addition, IPC messages sometimes need multi-layer forwarding during transmission between different FUs. Too long IPC messages will also place a heavy burden on the bus during message transmission, thereby affecting transmission performance and transmission efficiency.
为了至少解决部分上述问题，在本实施例中，可以对目标传输消息中记录的内存地址的格式进行重构，不再直接记录完整的内存地址，而是通过记录内存地址对应的标识值，实现对消息结构中内存地址占用的Dword数的压缩和优化。In order to solve at least part of the above-mentioned problems, in this embodiment, the format of the memory address recorded in the target transmission message can be reconstructed, and the complete memory address is no longer directly recorded, but the identification value corresponding to the memory address is recorded, so as to realize the compression and optimization of the number of Dwords occupied by the memory address in the message structure.
在本实施例中，可以根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值，得到目标标识值。这里，基地址可以作为内存地址的起始地址。目标标识值可以用于标识目标内存地址。In this embodiment, the identification value of the address identification corresponding to the target memory address may be determined according to the base address and the size of the address unit to obtain the target identification value. Here, the base address can be used as the starting address of the memory address. A target identification value can be used to identify a target memory address.
可选地，目标标识值可以是根据目标内存地址的大小与基地址和地址单元大小有关。基地址和地址单元大小可以是预先设定的固定值，即，每个内存地址对应的基地址和地址单元大小可以是一样的。Optionally, the target identification value may be related to the base address and address unit size according to the size of the target memory address. The base address and address unit size may be preset fixed values, that is, the base address and address unit size corresponding to each memory address may be the same.
可选地，基地址和地址单元的设定可以是在每次进行消息传输之前进行一次基地址和地址单元的设定，也可以是在如内存初始化时等准备阶段完成的，对应地，不论进行多少次消息传输，基地址和地址单元的设定可以只需要进行一次。Optionally, the setting of the base address and the address unit may be performed once before each message transmission, or may be completed during a preparation stage such as memory initialization. Correspondingly, no matter how many times the message transmission is performed, the setting of the base address and the address unit may only need to be performed once.
步骤S206，将目标标识值写入到目标传输消息的消息结构体，并将目标传输消息传输给目标传输消息的接收端。Step S206, write the target identification value into the message structure of the target transfer message, and transmit the target transfer message to the receiving end of the target transfer message.
对于待传输的目标传输消息可以包括消息结构体，消息结构体是用于写入消息中所携带的信息的结构体，在得到目标标识值之后，可以将目标标识值写入到目标传输消息的消息结构体，并将目标传输消息传输给目标传输消息的接收端。传输目标传输消息的方式可以包括传输目标传输消息的消息结构体，还可以包括传输目标传输消息除了消息结构体以外的其他信息。通过将内存地址对应的标识值写入到传输消息的消息结构体中，相较于传输直接地址的方式，可以实现缩小内存地址在传输消息中所占的比特数的目的，从而可以减小传输消息的长度（即，所占的比特数），提高带宽利用率。The target transmission message to be transmitted may include a message structure, and the message structure is a structure for writing information carried in the message. After the target identification value is obtained, the target identification value may be written into the message structure of the target transmission message, and the target transmission message is transmitted to the receiving end of the target transmission message. The manner in which the transmission target transmits the message may include the message structure of the transmission target's transmission message, and may also include other information other than the message structure of the transmission target's transmission message. By writing the identification value corresponding to the memory address into the message structure of the transmission message, compared with the way of transmitting the direct address, the purpose of reducing the number of bits occupied by the memory address in the transmission message can be achieved, thereby reducing the length of the transmission message (that is, the number of bits occupied), and improving bandwidth utilization.
这里，目标传输消息的消息结构体中可以包含多种参数，多种参数的顺序和位置可以是预先设定的。多种参数中的每种参数可以对应于该消息结构体中的一个字段，每种参数对应于一个或多个比特位，即，占用一个或多个比特位，每种参数所占用的比特位数可以是固定的，也可以是针对不同传输消息对应设置的。目标内存地址可以属于多种参数中的一种，可以在消息结构体中与目标内存地址对应的写入位置写入目标标识值。Here, the message structure of the target transmission message may contain various parameters, and the sequence and position of the various parameters may be preset. Each of the various parameters may correspond to a field in the message structure, each parameter corresponds to one or more bits, that is, occupies one or more bits, and the number of bits occupied by each parameter may be fixed or set correspondingly for different transmission messages. The target memory address can belong to one of various parameters, and the target identification value can be written in the writing position corresponding to the target memory address in the message structure.
通过上述步骤，通过获取目标内存地址，其中，目标内存地址为待传输的目标传输消息所传输的、目标缓冲区的缓冲区地址；根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值，得到目标标识值；将目标标识值写入到目标传输消息的消息结构体，并将目标传输消息传输给目标传输消息的接收端，可以解决相关技术中的进程间通信消息的传输方法存在由于需要传输的消息过长导致的消息传输效率低的问题，达到提高消息传输性能的技术效果。Through the above steps, by obtaining the target memory address, wherein the target memory address is the buffer address of the target buffer that is transmitted by the target transfer message to be transmitted; according to the base address and the size of the address unit, determine the identification value of the address identification corresponding to the target memory address, and obtain the target identification value; write the target identification value into the message structure of the target transmission message, and transmit the target transmission message to the receiving end of the target transmission message, which can solve the problem of low message transmission efficiency due to the excessive length of the message that needs to be transmitted in the inter-process communication message transmission method in the related art. effect.
在一个示范性实施例中，在根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值之前，上述方法还包括：获取基地址和地址单元大小，其中，基地址和地址单元大小是在进行内存初始化的过程中设置的。In an exemplary embodiment, before determining the identification value of the address identification corresponding to the target memory address according to the base address and the size of the address unit, the method further includes: obtaining the base address and the size of the address unit, wherein the base address and the size of the address unit are set during memory initialization.
在确定目标标识值之前，可以先获取基地址和地址单元大小。这里，基地址和地址单元大小可以是在进行内存初始化的过程中设置的。内存初始化指的是将管理多个进程的数据的内存进行的初始化。Before determining the target identification value, the base address and address unit size can be obtained first. Here, the base address and address unit size may be set during memory initialization. The memory initialization refers to the initialization of the memory that will manage the data of multiple processes.
通过本实施例，在内存初始化的过程中完成对基地址和地址单元的设置，可以避免浪费单独的资源进行基地址和地址单元的设定，从而提高资源的利用率。Through this embodiment, the setting of the base address and address unit is completed in the process of memory initialization, which can avoid wasting separate resources for setting the base address and address unit, thereby improving resource utilization.
在一个示范性实施例中，上述方法还包括：将缓冲区地址的最小值，设置为基地址，以及将存储地址间的最小单元，设置为地址单元大小。In an exemplary embodiment, the above method further includes: setting the minimum value of the buffer address as the base address, and setting the minimum unit between storage addresses as the address unit size.
在设置基地址和地址单元大小时，可以将缓冲区地址的最小值设置为基地址，将存储地址间的最小单元设置为地址单元大小。例如，内存初始化时定义BaseAddr（基地址）、UnitSize（地址单元大小），BaseAddr采用所用buffer地址的最小值，UnitSize为存储地址间的最小单元。When setting the base address and address unit size, the minimum value of the buffer address can be set as the base address, and the minimum unit between storage addresses can be set as the address unit size. For example, BaseAddr (base address) and UnitSize (address unit size) are defined during memory initialization. BaseAddr adopts the minimum value of the buffer address used, and UnitSize is the smallest unit between storage addresses.
可选地，地址单元大小为地址单元的长度（或者说，地址单元所占的比特位数），将存储地址间的最小单元，设置为地址单元大小是指：将存储地址间的最小单元的大小，设置为地址单元大小，地址单元为存储地址间的最小单元。Optionally, the size of the address unit is the length of the address unit (or in other words, the number of bits occupied by the address unit), and setting the smallest unit between storage addresses as the address unit size means: setting the size of the smallest unit between storage addresses as the size of the address unit, and the address unit is the smallest unit between storage addresses.
通过本实施例，将缓冲区地址的最小值设置为基地址，将存储地址间的最小单元设置为地址单元大小，可以提高基地址和地址单元大小对所有内存地址的适用性。Through this embodiment, the minimum value of the buffer address is set as the base address, and the minimum unit between storage addresses is set as the size of the address unit, which can improve the applicability of the base address and the size of the address unit to all memory addresses.
在一个示范性实施例中，获取基地址和地址单元大小，包括：从预设寄存器中读取出基地址和地址单元大小。In an exemplary embodiment, obtaining the base address and the size of the address unit includes: reading the base address and the size of the address unit from a preset register.
在本实施例中，对于基地址和地址单元大小，在硬件支持的条件下，可以将基地址和地址单元大小在定义完成后存储在预设寄存器中，例如，在对内存进行初始化时，设置基地址和地址单元大小，并将设置的基地址和地址单元大小存储到预设寄存器中。对应地，在进行消息传输时，可以从预设寄存器中读取出基地址和地址单元大小。这里，预设寄存器可以是预先设定的、可以包含具有存储功能的触发器的寄存器。In this embodiment, for the base address and the size of the address unit, under the condition of hardware support, the base address and the size of the address unit can be stored in the preset register after the definition is completed, for example, when the memory is initialized, the base address and the size of the address unit are set, and the set base address and the size of the address unit are stored in the preset register. Correspondingly, during message transmission, the base address and address unit size can be read from the preset register. Here, the preset register may be a preset register that may include a flip-flop with a storage function.
预设寄存器可以仅在内存初始化时允许被设置、修改等，或者，在进行消息传输的过程中不允许被设置、修改等。在此情况下，在将基地址和地址单元大小存储到预设寄存器之后，在不同的发送端想要进行传输消息传输时，均可从预设寄存器中读取基地址和地址单元大小。可选地，为避免信息获取冲突，预设寄存器在同一时间仅允许一个进程进行数据读取，同时，在读取数据时不允许其他进程从预设寄存器中读取数据。或者，预设寄存器在同一时间也可以允许多个进程进行数据读取，此时可以通过一种或多个方式避免数据读取冲突，比如，预设寄存器中的信息仅允许读取，不允许修改等。本实施例中对此不做限定。The preset register may only be allowed to be set, modified, etc. during memory initialization, or may not be allowed to be set, modified, etc. during message transmission. In this case, after the base address and the size of the address unit are stored in the preset register, when different senders intend to transmit messages, they can read the base address and the size of the address unit from the preset register. Optionally, in order to avoid information acquisition conflicts, the preset register only allows one process to read data at a time, and at the same time, other processes are not allowed to read data from the preset register when reading data. Alternatively, the preset register can also allow multiple processes to read data at the same time. At this time, one or more methods can be used to avoid data read conflicts. For example, the information in the preset register is only allowed to be read and not allowed to be modified. This is not limited in this embodiment.
需要说明的是，不同的进程在进行传输消息传输时，均可从预设寄存器中读取出基地址和地址单元大小，不同进程所读取到的基地址和地址单元大小可以是相同的。It should be noted that, when different processes transmit messages, they can read the base address and address unit size from the preset register, and the base address and address unit size read by different processes may be the same.
通过本实施例，通过从寄存器中读取基地址和地址单元大小，可以便于获取基地址和地址单元大小，从而提高信息获取的便捷性。Through this embodiment, by reading the base address and the size of the address unit from the register, the base address and the size of the address unit can be obtained conveniently, thereby improving the convenience of information acquisition.
在一个示范性实施例中，根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值，得到目标标识值，包括：确定目标内存地址与基地址之间的地址偏移量，得到目标偏移量；根据目标偏移量和地址单元大小，确定与目标内存地址对应的地址标识的目标标识值。In an exemplary embodiment, according to the base address and the size of the address unit, determining the identification value of the address identification corresponding to the target memory address to obtain the target identification value includes: determining the address offset between the target memory address and the base address to obtain the target offset; according to the target offset and the size of the address unit, determining the target identification value of the address identification corresponding to the target memory address.
由于内存地址的实际地址可以由基地址和偏移地址所确定，在确定目标标识值时，考虑基地址的独特作用（定位排布），可以先确定目标内存地址与基地址之间的地址偏移量，得到目标偏移量，再根据目标偏移量和地址单元大小，确定与目标内存地址对应的地址标识的目标标识值。这里的目标偏移量可以是目标内存地址与基地址的大小的差值，即，前述偏移地址。Since the actual address of the memory address can be determined by the base address and the offset address, when determining the target identification value, the unique role of the base address (location arrangement) can be considered. The address offset between the target memory address and the base address can be determined first to obtain the target offset, and then the target identification value of the address identification corresponding to the target memory address can be determined according to the target offset and the size of the address unit. The target offset here may be the difference between the size of the target memory address and the base address, that is, the aforementioned offset address.
通过本实施例，根据内存地址和基地址的偏移量与地址单元大小的关系确定内存地址对应的标识值，可以提高标识值与内存地址之间的关联性，便于传输消息的接收端内存地址的获取。Through this embodiment, the identification value corresponding to the memory address is determined according to the relationship between the offset of the memory address and the base address and the size of the address unit, which can improve the correlation between the identification value and the memory address, and facilitate the acquisition of the memory address of the receiving end of the transmission message.
在一个示范性实施例中，根据目标偏移量和地址单元大小，确定与目标内存地址对应的地址标识的目标标识值，包括：将目标偏移量除以地址单元大小所得到的商，确定为与目标内存地址对应的地址标识的目标标识值。In an exemplary embodiment, determining the target identifier value of the address identifier corresponding to the target memory address according to the target offset and the address unit size includes: determining a quotient obtained by dividing the target offset by the address unit size as the target identifier value of the address identifier corresponding to the target memory address.
在本实施例中，由于地址单元大小可以是存储地址间的最小单元，可以认为存储的每个地址占用整数数量的地址单元，即，每个地址的大小是地址单元大小的整数倍。可以将目标偏移量除以地址单元大小所得到的商，确定为与目标内存地址对应的地址标识的目标标识值。In this embodiment, since the address unit size can be the smallest unit among storage addresses, it can be considered that each stored address occupies an integer number of address units, that is, the size of each address is an integer multiple of the address unit size. A quotient obtained by dividing the target offset by the size of the address unit may be determined as the target identification value of the address identification corresponding to the target memory address.
例如，发送端获取到BufferAddr后，计算该BufferAddr相对于基地址的相对偏移量，偏移值bufferId=(BufferAddr–BaseAddr)/UnitSize，运算后得到的bufferId一般不超过12bits。For example, after the sender obtains the BufferAddr, it calculates the relative offset of the BufferAddr relative to the base address, the offset value bufferId=(BufferAddr–BaseAddr)/UnitSize, and the bufferId obtained after the operation generally does not exceed 12 bits.
通过本实施例，根据内存地址和基地址的偏移量与地址单元大小的商确定内存地址对应的标识值，可以提高确定标识值的便捷性。Through this embodiment, the identification value corresponding to the memory address is determined according to the quotient of the offset between the memory address and the base address and the size of the address unit, which can improve the convenience of determining the identification value.
在一个示范性实施例中，上述方法还包括：根据目标缓冲区的缓冲区大小和地址单元大小，确定与目标内存地址对应的缓冲区长度参数的参数值，得到目标长度值。对应地，将目标标识值写入到目标传输消息的消息结构体，包括：将目标标识值和目标长度值写入到目标传输消息的消息结构体。In an exemplary embodiment, the above method further includes: according to the buffer size and address unit size of the target buffer, determining a parameter value of a buffer length parameter corresponding to the target memory address to obtain a target length value. Correspondingly, writing the target identification value into the message structure of the target transmission message includes: writing the target identification value and the target length value into the message structure of the target transmission message.
为了便于目标传输消息的接收端可以准确确定与目标内存地址对应的缓冲区完整信息，可以将目标内存地址对应的长度值也写入目标传输消息的消息结构体中。在本实施例中，可以根据目标缓冲区的缓冲区大小和地址单元大小，确定与目标内存地址对应的缓冲区长度参数的参数值，得到目标长度值。In order to facilitate the receiver of the target transfer message to accurately determine the complete information of the buffer corresponding to the target memory address, the length value corresponding to the target memory address can also be written into the message structure of the target transfer message. In this embodiment, the parameter value of the buffer length parameter corresponding to the target memory address may be determined according to the buffer size and address unit size of the target buffer to obtain the target length value.
在将目标标识值写入到目标传输消息的消息结构体的同时，可以将目标长度值也写入到目标传输消息的消息结构体中。例如，发送端可以将获取到的bufferId、bufferLength填进IPC消息结构体内。While writing the target identification value into the message structure of the target transmission message, the target length value can also be written into the message structure of the target transmission message. For example, the sender can fill the obtained bufferId and bufferLength into the IPC message structure.
可选地，目标标识值和目标长度值可以作为一个内存地址参数在目标传输消息的消息结构体中前后相邻。可以是目标标识值在前，目标长度值在后，也可以是目标长度值在前，目标标识值在后，本实施例对此不做限定。这里，地址标识可以用于标识缓冲区的内存地址（绝对地址），而缓冲区长度参数（或者称缓冲区长度标识）可以用于标识缓冲区的缓冲区大小，通过这两个参数，可以确定出对应的缓冲区。Optionally, the target identification value and the target length value may be used as a memory address parameter adjacent to each other in the message structure of the target transmission message. It may be that the target identification value comes first and the target length value follows, or the target length value comes first and the target identification value follows, which is not limited in this embodiment. Here, the address identifier can be used to identify the memory address (absolute address) of the buffer, and the buffer length parameter (or buffer length identifier) can be used to identify the buffer size of the buffer. Through these two parameters, the corresponding buffer can be determined.
通过本实施例，将内存地址对应的长度值与内存地址对应的标识值一起写入消息结构体中，可以提高缓冲区定位的边界性，提供信息传输的准确性。Through this embodiment, writing the length value corresponding to the memory address and the identification value corresponding to the memory address into the message structure can improve the boundary of buffer location and improve the accuracy of information transmission.
在一个示范性实施例中，根据目标缓冲区的缓冲区大小和地址单元大小，确定与目标内存地址对应的缓冲区长度参数的参数值，得到目标长度值，包括：将目标缓冲区的缓冲区大小除以地址单元大小所得到的商，确定为与目标内存地址对应的缓冲区长度参数的目标长度值。In an exemplary embodiment, according to the buffer size and address unit size of the target buffer, determining the parameter value of the buffer length parameter corresponding to the target memory address to obtain the target length value includes: dividing the buffer size of the target buffer by the address unit size to determine the target length value of the buffer length parameter corresponding to the target memory address.
在本实施例中，在确定目标内存地址对应的长度值时，可以将目标缓冲区的缓冲区大小除以地址单元大小所得到的商，确定为与目标内存地址对应的缓冲区长度参数的目标长度值。这里，内存地址对应的长度值是指内存地址对应的缓冲区长度参数的长度值，即，可以用于标识内存地址对应的缓冲区的大小。In this embodiment, when determining the length value corresponding to the target memory address, the quotient obtained by dividing the buffer size of the target buffer by the address unit size may be determined as the target length value of the buffer length parameter corresponding to the target memory address. Here, the length value corresponding to the memory address refers to the length value of the buffer length parameter corresponding to the memory address, that is, it can be used to identify the size of the buffer corresponding to the memory address.
例如，bufferLength（可以用于标识缓冲区大小的参数）可以根据需要传输的buffer大小除以UnitSize获取，一般所占bits较小。For example, bufferLength (a parameter that can be used to identify the size of the buffer) can be obtained by dividing the buffer size to be transmitted by UnitSize, and generally occupies less bits.
通过本实施例，将缓冲区的缓冲区大小与地址单元大小的商确定为消息结构体中写入的长度值，可以便于接收端根据预设的地址单元大小确定完整的缓冲区信息，提高消息传输的准确性。Through this embodiment, the quotient of the buffer size of the buffer and the address unit size is determined as the length value written in the message structure, which can facilitate the receiving end to determine complete buffer information according to the preset address unit size, and improve the accuracy of message transmission.
在一个示范性实施例中，将目标标识值和目标长度值写入到目标传输消息的消息结构体，包括：按照目标标识值所占的比特数和目标长度值所占用的比特数，将目标标识值和目标长度值写入到目标传输消息的消息结构体。In an exemplary embodiment, writing the target identification value and the target length value into the message structure of the target transmission message includes: writing the target identification value and the target length value into the message structure of the target transmission message according to the number of bits occupied by the target identification value and the number of bits occupied by the target length value.
对于确定的目标标识值和目标长度值，可以分别确定两者在目标传输消息的消息结构体中的比特数，按照目标标识值所占的比特数和目标长度值所占用的比特数，将目标标识值和目标长度值写入到目标传输消息的消息结构体。For the determined target identification value and target length value, the number of bits in the message structure of the target transmission message can be determined respectively, and the target identification value and the target length value are written into the message structure of the target transmission message according to the number of bits occupied by the target identification value and the number of bits occupied by the target length value.
通过本实施例，按照标识值和长度值所占的比特数完成在消息结构体中的写入，可以有效减小内存地址在消息结构体中占用的比特数，实现减小消息长度的目的。Through this embodiment, the writing in the message structure is completed according to the number of bits occupied by the identification value and the length value, which can effectively reduce the number of bits occupied by the memory address in the message structure and achieve the purpose of reducing the message length.
在一个示范性实施例中，上述方法还包括：根据目标内存地址所占用的比特数，动态调整目标标识值所占的比特数和目标长度值所占的比特数。In an exemplary embodiment, the above method further includes: dynamically adjusting the number of bits occupied by the target identification value and the number of bits occupied by the target length value according to the number of bits occupied by the target memory address.
对于目标标识值和目标长度值在目标传输消息的消息结构体中所占的比特数，可以根据实际场景动态调整。在本实施例中，可以根据目标内存地址所占用的比特数，动态调整目标标识值所占的比特数和目标长度值所占的比特数。The number of bits occupied by the target identification value and the target length value in the message structure of the target transmission message can be dynamically adjusted according to actual scenarios. In this embodiment, the number of bits occupied by the target identification value and the number of bits occupied by the target length value may be dynamically adjusted according to the number of bits occupied by the target memory address.
可选地，上述目标标识值所占的比特数和目标长度所占的比特数可以根据当前的传输环境，结合对应的内存地址等参数的大小，由发送端和接收端预先确定目标标识值所占的比特数和目标长度所占的比特数。Optionally, the above-mentioned number of bits occupied by the target identification value and the number of bits occupied by the target length can be determined in advance by the sending end and the receiving end according to the current transmission environment and in combination with the size of parameters such as the corresponding memory address. The number of bits occupied by the target identification value and the number of bits occupied by the target length.
例如，为方便获取传输消息中携带的信息，一个Dword可以存储两组bufferId和bufferLength，此时在同样消息长度下则可以存放更多地址。For example, in order to conveniently obtain the information carried in the transmission message, a Dword can store two sets of bufferId and bufferLength, and at this time, more addresses can be stored under the same message length.
通过本实施例，通过动态调整标识值所占比特数和长度值所占比特数，可以实现在不增加消息长度的情况下传输更多的内存地址，从而提高消息结构体的利用率。Through this embodiment, by dynamically adjusting the number of bits occupied by the identification value and the number of bits occupied by the length value, more memory addresses can be transmitted without increasing the length of the message, thereby improving the utilization rate of the message structure.
在一个示范性实施例中，根据目标内存地址所占用的比特数，动态调整目标标识值所占的比特数和目标长度值所占的比特数，包括：将目标内存地址所占用的比特数与预设比例的乘积，确定为目标标识值所占的比特数，将目标内存地址所占用的比特数与目标标识值所占的比特数的差值，确定为目标长度值所占的比特数。In an exemplary embodiment, dynamically adjusting the number of bits occupied by the target identification value and the number of bits occupied by the target length value according to the number of bits occupied by the target memory address includes: determining the product of the number of bits occupied by the target memory address and a preset ratio as the number of bits occupied by the target identification value, and determining the difference between the number of bits occupied by the target memory address and the number of bits occupied by the target identification value as the number of bits occupied by the target length value.
对于标识值和长度值所占比特数的动态调整，可以预先设定一个比例，即，预设比例，根据预设比例计算确定标识值所占的比特数和长度值所占的比特数。在本实施例中，可以将目标内存地址所占用的比特数与预设比例的乘积，确定为目标标识值所占的比特数，将目标内存地址所占用的比特数与目标标识值所占的比特数的差值，确定为目标长度值所占的比特数。For the dynamic adjustment of the number of bits occupied by the identification value and the length value, a ratio can be preset, that is, a preset ratio, and the number of bits occupied by the identification value and the number of bits occupied by the length value are calculated and determined according to the preset ratio. In this embodiment, the product of the number of bits occupied by the target memory address and the preset ratio can be determined as the number of bits occupied by the target identification value, and the difference between the number of bits occupied by the target memory address and the number of bits occupied by the target identification value can be determined as the number of bits occupied by the target length value.
例如，在将获取到的bufferId、bufferLength填进IPC消息结构体内时，可以根据buffer所占bit数动态调整各自所占的比特数，比如，bufferId占用12bits，bufferLength占用4bits。For example, when filling the obtained bufferId and bufferLength into the IPC message structure, the number of bits occupied by each buffer can be dynamically adjusted according to the number of bits occupied by the buffer. For example, bufferId occupies 12 bits, and bufferLength occupies 4 bits.
通过本实施例，通过预设比例实现标识值和长度值所占比特数的动态调整，可以提高调整的效率，从而提高消息传输的效率。Through this embodiment, the dynamic adjustment of the number of bits occupied by the identification value and the length value is realized through the preset ratio, which can improve the efficiency of adjustment, thereby improving the efficiency of message transmission.
在一个示范性实施例中，根据基地址和地址单元大小，确定与目标内存地址对应的地址标识的标识值，得到目标标识值，包括：在目标内存地址包含多个内存地址的情况下，根据基地址和地址单元大小，分别确定与多个内存地址中的每个内存地址对应的地址标识的标识值，得到与每个内存地址对应的标识值，其中，目标标识值包括与每个内存地址对应的标识值。In an exemplary embodiment, determining an identification value of an address identification corresponding to the target memory address according to the base address and the size of the address unit to obtain the target identification value includes: when the target memory address includes multiple memory addresses, according to the base address and the size of the address unit, respectively determining the identification value of the address identification corresponding to each memory address in the multiple memory addresses to obtain an identification value corresponding to each memory address, wherein the target identification value includes an identification value corresponding to each memory address.
由于NAND技术中的地址信息的数量与NAND的容量呈正相关的关系，IPC消息一般包含多个内存地址，在本实施例中，在目标内存地址包含多个内存地址的情况下，前述目标标识值可以包括与每个内存地址对应的标识值，根据基地址和地址单元大小，可以分别确定与多个内存地址中的每个内存地址对应的地址标识的标识值，得到与每个内存地址对应的标识值。Since the quantity of address information in the NAND technology is positively correlated with the capacity of the NAND, the IPC message generally includes a plurality of memory addresses. In this embodiment, when the target memory address includes a plurality of memory addresses, the aforementioned target identification value can include an identification value corresponding to each memory address. According to the base address and the size of the address unit, the identification value of the address identification corresponding to each memory address in the plurality of memory addresses can be determined respectively, and the identification value corresponding to each memory address can be obtained.
可选地，可以按照前述确定目标标识值的方式，确定内存地址与基地址之间的地址偏移量，将地址偏移量除以地址单元大小所得到的商，确定为与内存地址对应的地址标识的标识值。Optionally, the address offset between the memory address and the base address can be determined according to the aforementioned method for determining the target identification value, and the quotient obtained by dividing the address offset by the size of the address unit can be determined as the identification value of the address identification corresponding to the memory address.

通过本实施例，在存在多个内存地址的情况下，分别根据基地址和地址单元大小确定与每个内存地址对应的标识值，可以提高接收端对多个内存地址的识别率，从而提高内存地址传输的准确性。Through this embodiment, in the case of multiple memory addresses, the identification value corresponding to each memory address is determined according to the base address and the size of the address unit, which can improve the recognition rate of the receiving end for multiple memory addresses, thereby improving the accuracy of memory address transmission.
在一个示范性实施例中，获取目标内存地址，包括：获取目标缓冲区的绝对地址，得到目标内存地址。In an exemplary embodiment, obtaining the target memory address includes: obtaining the absolute address of the target buffer to obtain the target memory address.
为了避免消息传输过程中的内存地址因断链等原因出现地址失效的情况发生，在本实施例中，目标传输消息中传输的内存地址可以是绝对地址，即文件的绝对位置。获取目标内存地址可以是指获取目标缓冲区的绝对地址。In order to prevent the memory address from becoming invalid due to link disconnection during message transmission, in this embodiment, the memory address transmitted in the target transmission message may be an absolute address, that is, the absolute location of the file. Obtaining the target memory address may refer to obtaining the absolute address of the target buffer.
通过本实施例，获取绝对地址作为待传输的内存地址，可以避免因连接位置的改变导致地址失效，可以提高内存地址传输的有效性。Through this embodiment, the absolute address is obtained as the memory address to be transmitted, which can avoid address invalidation caused by the change of the connection position, and can improve the effectiveness of memory address transmission.
根据本申请实施例的另一个方面，还提供了一种消息的传输方法，其可以是用于接收并处理通过前述实施例中提供的消息的传输方法所产生并发送的传输消息。以由计算机终端来执行本实施例中的消息的传输方法为例，图3是根据本申请实施例的另一种消息的传输方法的流程图，如图3所示，该流程包括如下步骤：According to another aspect of the embodiments of the present application, a message transmission method is also provided, which may be used to receive and process the transmission message generated and sent by the message transmission method provided in the foregoing embodiments. Taking the computer terminal to execute the message transmission method in this embodiment as an example, FIG. 3 is a flowchart of another message transmission method according to the embodiment of the present application. As shown in FIG. 3 , the process includes the following steps:
步骤S302，接收发送端发送的目标传输消息。Step S302, receiving the target transfer message sent by the sender.
在本实施例中，在进程间通信中，对于一个传输消息的接收端，比如，目标传输消息的接收端，其可以接收发送端发送的目标传输消息。这里，接收到的目标传输消息可以是由发送端生成的、且其消息结构体中写入了目标标识值。In this embodiment, in inter-process communication, for a receiver of a transfer message, for example, a receiver of a target transfer message, it may receive the target transfer message sent by the sender. Here, the received target transfer message may be generated by the sender, and the target identification value is written in its message structure.
步骤S304，从目标传输消息的消息结构体中提取出目标标识值，其中，目标标识值是与目标内存地址对应的地址标识的标识值。Step S304, extracting the target identification value from the message structure of the target transfer message, wherein the target identification value is the identification value of the address identification corresponding to the target memory address.
在接收端接收到目标传输消息之后，可以从目标传输消息的消息结构体中提取出目标标识值。这里，目标标识值可以是与目标内存地址对应的地址标识的标识值，其可以是从目标传输消息的消息结构体的指定字段或者指定位置提取出的，目标标识值的长度可以是固定的，也可以是可变的，可以基于所占的比特位数、结束标识或者其他信息，从目标传输消息的消息结构体的指定字段或者指定位置提取出的目标标识值。After receiving the target transmission message, the receiving end can extract the target identification value from the message structure of the target transmission message. Here, the target identification value may be the identification value of the address identification corresponding to the target memory address, which may be extracted from a specified field or a specified position of the message structure of the target transmission message. The length of the target identification value may be fixed or variable. The target identification value may be extracted from the specified field or specified position of the message structure of the target transmission message based on the number of bits occupied, the end identification or other information.
可选地，可以根据提取出的目标标识值确定对应的目标内存地址的地址标识，进而确定发送端想要传输的内存地址。Optionally, the address identifier of the corresponding target memory address can be determined according to the extracted target identifier value, and then the memory address that the sender wants to transmit can be determined.
可选地，若消息结构体中同时写入了目标标识值和与目标内存地址对应的长度值，即，目标长度值，在提取出目标标识值的同时，可以提取出对应的目标长度值，以根据目标长度值和目标长度值确定出与目标内存地址对应的缓冲区（即，buffer）。Optionally, if the target identification value and the length value corresponding to the target memory address are written in the message structure at the same time, that is, the target length value, when the target identification value is extracted, the corresponding target length value can be extracted, so as to determine the buffer (ie, buffer) corresponding to the target memory address according to the target length value and the target length value.
步骤S306，根据目标标识值、基地址和地址单元大小，确定出目标内存地址。Step S306, determine the target memory address according to the target identification value, the base address and the size of the address unit.
可选地，接收端可以通过与发送端获取基地址和地址单元大小相同或者类似的方式来获取基地址和地址单元大小，具体的获取方式可以参考前述实施例的描述，本实施例在此不做赘述。Optionally, the receiving end may obtain the base address and address unit size in the same or similar manner as the transmitting end obtains the base address and address unit size. For the specific obtaining method, refer to the description in the foregoing embodiments, and this embodiment will not repeat them here.
在提取出目标标识值之后，可以根据获取到的基地址、地址单元大小，结合目标标识值确定出目标内存地址。确定目标内存地址的方式可以与前述实施例中生成目标内存地址的方式对应。After the target identification value is extracted, the target memory address can be determined according to the obtained base address and address unit size combined with the target identification value. The manner of determining the target memory address may correspond to the manner of generating the target memory address in the foregoing embodiments.
通过上述步骤，通过接收发送端发送的目标传输消息；从目标传输消息的消息结构体中提取出目标标识值，其中，目标标识值是与目标内存地址对应的地址标识的标识值；根据目标标识值、基地址和地址单元大小，确定出目标内存地址，可以解决相关技术中的进程间通信消息的传输方法存在由于需要传输的消息过长导致的消息传输效率低的问题，达到提高消息传输性能的技术效果。Through the above steps, by receiving the target transmission message sent by the sender; extracting the target identification value from the message structure of the target transmission message, wherein the target identification value is the identification value of the address identification corresponding to the target memory address; determining the target memory address according to the target identification value, the base address and the size of the address unit, which can solve the problem of low message transmission efficiency caused by too long messages to be transmitted in the inter-process communication message transmission method in the related art, and achieve the technical effect of improving message transmission performance.
在一个示范性实施例中，从目标传输消息的消息结构体中提取出目标标识值，包括：确定目标标识值所占的比特数和目标长度值所占的比特数，其中，目标长度值是与目标内存地址对应的缓冲区长度参数的参数值，目标长度值用于标识与目标内存地址所对应的目标缓冲区的缓冲区大小；根据目标标识值所占的比特数和目标长度值所占的比特数，从目标传输消息的消息结构体中提取出目标标识值和目标长度值。In an exemplary embodiment, extracting the target identification value from the message structure of the target transfer message includes: determining the number of bits occupied by the target identification value and the number of bits occupied by the target length value, wherein the target length value is a parameter value of a buffer length parameter corresponding to the target memory address, and the target length value is used to identify the buffer size of the target buffer corresponding to the target memory address; and extracting the target identification value and the target length value from the message structure of the target transmission message according to the number of bits occupied by the target identification value and the number of bits occupied by the target length value.
由于目标传输消息中各个参数可以是以不同的位置和比特数写入的消息结构体，在目标传输消息的消息结构体中写入有目标标识值和目标长度值的情况下，提取目标标识值和目标长度值的方式，可以是先确定目标标识值所占的比特数和目标长度值所占的比特数，再根据目标标识值所占的比特数和目标长度值所占的比特数，从目标传输消息的消息结构体中提取出目标标识值和目标长度值。这里，目标长度值是与目标内存地址对应的缓冲区长度参数的参数值，目标长度值用于标识与目标内存地址所对应的目标缓冲区的缓冲区大小。Since each parameter in the target transmission message may be a message structure written in a different position and number of bits, when the target identification value and the target length value are written in the message structure of the target transmission message, the method of extracting the target identification value and the target length value may be to first determine the number of bits occupied by the target identification value and the number of bits occupied by the target length value, and then extract the target identification value and the target length value from the message structure of the target transmission message according to the number of bits occupied by the target identification value and the number of bits occupied by the target length value. Here, the target length value is a parameter value of the buffer length parameter corresponding to the target memory address, and the target length value is used to identify the buffer size of the target buffer corresponding to the target memory address.
可选地，对于目标标识值所占的比特数和目标长度值所占的比特数，可以是由发送端在发送目标传输消息的同时发送至接收端的，对应地，可以通过发送前述预设比例等方式实现。此外，目标标识值所占的比特数和目标长度值所占的比特数，也可以是接收端和发送端两方在消息传输前共同确定的，即，接收端知道目标标识值所占的比特数和目标长度值所占的比特数，无需发送端告知。Optionally, the number of bits occupied by the target identification value and the number of bits occupied by the target length value may be sent by the sender to the receiver while sending the target transfer message, and correspondingly, it may be realized by sending the aforementioned preset ratio. In addition, the number of bits occupied by the target identification value and the number of bits occupied by the target length value can also be jointly determined by both the receiving end and the sending end before message transmission, that is, the receiving end knows the number of bits occupied by the target identification value and the number of bits occupied by the target length value without notification from the sending end.
通过本实施例，根据标识值所占的比特数和长度值所占的比特数进行标识值和目标长度值的提取，可以提高标识值和长度值获取的准确性。Through this embodiment, the identification value and the target length value are extracted according to the number of bits occupied by the identification value and the number of bits occupied by the length value, which can improve the accuracy of obtaining the identification value and the length value.
在一个示范性实施例中，根据目标标识值、基地址和地址单元大小，确定出目标内存地址，包括：将目标标识值与地址单元大小的乘积、与基地址的和，确定为目标内存地址。In an exemplary embodiment, determining the target memory address according to the target identification value, the base address and the size of the address unit includes: determining the sum of the product of the target identification value and the size of the address unit and the base address as the target memory address.
在本实施例中，目标标识值可以为目标内存地址与基地址之间的地址偏移量除以地址单元大小所得到的商（即，bufferId = (BufferAddr – BaseAddr) / UnitSize），接收端可以将目标标识值与地址单元大小的乘积、与基地址的和，确定为目标内存地址，即，按照计算公式BufferAddr = bufferId*UnitSize+ BaseAddr来确定目标内存地址。In this embodiment, the target identification value may be the quotient obtained by dividing the address offset between the target memory address and the base address by the size of the address unit (that is, bufferId = (BufferAddr - BaseAddr) / UnitSize), and the receiving end may determine the sum of the product of the target identification value and the size of the address unit and the base address as the target memory address, that is, determine the target memory address according to the calculation formula BufferAddr = bufferId*UnitSize + BaseAddr.
通过本实施例，根据标识值与地址单元大小的乘积、与基地址的和确定内存地址，可以在减小目标内存地址在目标传输消息内的比特数的同时，提高目标内存地址传输的准确性。Through this embodiment, the memory address is determined according to the product of the identification value and the size of the address unit, and the sum of the base address, which can improve the accuracy of the target memory address transmission while reducing the number of bits of the target memory address in the target transmission message.
在一个示范性实施例中，在根据目标标识值、基地址和地址单元大小，确定出目标内存地址之后，上述方法还包括：对目标内存地址进行合法性检查，得到合法性检查结果；在合法性检查结果指示目标内存地址合法的情况下，保存目标内存地址，并释放目标传输消息；在合法性检查结果指示目标内存地址不合法的情况下，向发送端发送消息异常指示信息，并释放目标传输消息，其中，消息异常指示信息用于指示目标传输消息中所传输的内存地址异常。In a demonstration embodiment, after determining the target memory address according to the target identification value, base address, and address unit size, the above method also includes: the target memory address is checked to obtain the results of the legitimacy inspection; the target memory address is stored and the target transmission message is released; In the case of the law, send message anomalies to the sender and release the target transmission message. Among them, the message anomaly indicates that the memory address is abnormal in the transmission of the transmission message in the target.
为了提高消息传输的安全性，避免因传输的内存地址不合法等情况对接收端造成影响，在本实施例中，在确定出目标内存地址之后，可以对目标内存地址进行合法性检查，并得到合法性检查结果。In order to improve the security of message transmission and avoid the impact on the receiving end due to the illegality of the transmitted memory address, in this embodiment, after the target memory address is determined, a legality check can be performed on the target memory address, and the result of the legality check can be obtained.
在合法性检查结果指示目标内存地址合法的情况下，可以保存目标内存地址，并释放目标传输消息。在合法性检查结果指示目标内存地址不合法的情况下，可以向发送端发送消息异常指示信息，并释放目标传输消息。这里，消息异常指示信息可以用于指示目标传输消息中所传输的内存地址异常。If the result of the validity check indicates that the target memory address is legal, the target memory address may be saved, and the target transfer message may be released. In the case that the result of the legality check indicates that the target memory address is illegal, message exception indication information may be sent to the sender, and the target transfer message may be released. Here, the message abnormal indication information may be used to indicate that the memory address transmitted in the target transmission message is abnormal.
例如，以目标传输消息为IPC消息为例，在得到BufferAddr之后，接收端可以对BufferAddr进行参数检查，合法则直接使用该BufferAddr并释放IPC消息，并继续处理下一步，不合法则返回异常并释放IPC消息。For example, if the target transmission message is an IPC message, after obtaining the BufferAddr, the receiving end can check the parameters of the BufferAddr. If it is legal, it will directly use the BufferAddr and release the IPC message, and continue to process the next step. If it is not legal, it will return an exception and release the IPC message.
通过本实施例，通过对确定的内存地址进行合法性检查，可以避免不合法的内存地址导致传输的消息无效或对接收端造成影响等情况发生，可以提高消息传输的有效性。Through this embodiment, by checking the validity of the determined memory address, it is possible to avoid situations such as invalidity of the transmitted message caused by an illegal memory address or an impact on the receiving end, and the effectiveness of message transmission can be improved.
在一个示范性实施例中，对目标内存地址进行合法性检查，得到合法性检查结果，包括：在目标内存地址位于预设地址范围内的情况下，确定目标内存地址合法；在目标内存地址位于预设地址范围以外的情况下，确定目标内存地址不合法。In an exemplary embodiment, performing a legality check on the target memory address to obtain a legality check result includes: determining that the target memory address is legal if the target memory address is within a preset address range; determining that the target memory address is illegal if the target memory address is outside the preset address range.
对目标内存地址进行的合法性检查，可以是检查目标内存地址的大小是否位于预期的范围之内。在本实施例中，可以预先设定一个地址范围，即，预设地址范围，用于判断确定的内存地址是否合法。The legality check performed on the target memory address may be to check whether the size of the target memory address is within an expected range. In this embodiment, an address range may be preset, that is, a preset address range for judging whether the determined memory address is legal.
在目标内存地址位于预设地址范围内的情况下，可以确定目标内存地址合法。而在目标内存地址位于预设地址范围以外的情况下，可以确定目标内存地址不合法。When the target memory address is within the preset address range, it can be determined that the target memory address is legal. If the target memory address is outside the preset address range, it can be determined that the target memory address is illegal.
通过本实施例，通过预先设定内存地址的地址范围、并检查内存地址是否位于该地址范围之内来确定确定的内存地址是否合法，可以提高合法检查的效率，从而提高消息传输的效率。Through this embodiment, by presetting the address range of the memory address and checking whether the memory address is within the address range to determine whether the determined memory address is legal, the efficiency of legal checking can be improved, thereby improving the efficiency of message transmission.
下面结合可选示例对本申请实施例中的消息的传输方法进行解释说明。在本可选示例中，目标传输消息为IPC消息，目标内存地址为BufferAddr（即，buffer地址），目标传输消息为IPC消息，基地址为BaseAddr，地址单元大小为UnitSize。The message transmission method in the embodiment of the present application is explained below in combination with optional examples. In this optional example, the target transmission message is an IPC message, the target memory address is BufferAddr (ie, buffer address), the target transmission message is an IPC message, the base address is BaseAddr, and the address unit size is UnitSize.
由于IPC消息在不同FU间传输过程中有时需要多层转发，消息长度过长会占用较大带宽并增加命令传输耗时。本可选示例中提供了一种提升IPC消息传输效率的方法，消息内不再填写绝对的64bit地址，采用bufferId加bufferLength形式进行消息的传输。传输时发送端根据已经定义的BaseAddr和UnitSize以及将要传递的buffer地址计算出bufferId和bufferLength并填入消息体内，接收端根据已经定义的BaseAddr和UnitSize以及收到的bufferId和bufferLength计算出buffer地址，即完成了地址的传输。通过上述简单计算，可以大大压缩BufferAddr在消息内的所占空间，原来2个Dword只能传输一个64bit的绝对地址，优化后大致能传输4个或更多的绝对地址。通过增加简单计算实现了消息长度的减小，优化了进程与进程之间的数据交互，提升了消息传输的效率，减小了不必要的传输带宽浪费，更有效地利用总线带宽，有助于提高产品性能。Because IPC messages sometimes need multi-layer forwarding during transmission between different FUs, too long message length will occupy a large bandwidth and increase the time-consuming command transmission. This optional example provides a method to improve the efficiency of IPC message transmission. The absolute 64-bit address is no longer filled in the message, and the message is transmitted in the form of bufferId plus bufferLength. During transmission, the sending end calculates the bufferId and bufferLength based on the defined BaseAddr and UnitSize and the buffer address to be transmitted and fills them in the message body, and the receiving end calculates the buffer address based on the defined BaseAddr and UnitSize as well as the received bufferId and bufferLength, that is, the transmission of the address is completed. Through the above simple calculation, the space occupied by BufferAddr in the message can be greatly reduced. Originally, two Dwords could only transmit one 64-bit absolute address. After optimization, it can roughly transmit four or more absolute addresses. By adding simple calculations, the length of the message is reduced, the data interaction between processes is optimized, the efficiency of message transmission is improved, unnecessary waste of transmission bandwidth is reduced, and bus bandwidth is used more effectively, which helps to improve product performance.
本可选示例中的消息的传输方法的流程可以包括以下步骤：The flow of the message transmission method in this optional example may include the following steps:
步骤1，内存初始化时定义BaseAddr、UnitSize。Step 1. Define BaseAddr and UnitSize when initializing the memory.
步骤2，发送端获取到BufferAddr后，计算该BufferAddr相对于基地址的相对偏移量，根据公式bufferId =(BufferAddr–BaseAddr)/UnitSize，确定bufferId，根据需要传输的buffer大小除以UnitSize获取bufferLength。Step 2: After obtaining the BufferAddr, the sender calculates the relative offset of the BufferAddr relative to the base address, determines the bufferId according to the formula bufferId = (BufferAddr–BaseAddr)/UnitSize, and divides the size of the buffer to be transmitted by the UnitSize to obtain the bufferLength.
步骤3，将获取到的bufferId、bufferLength填进IPC消息结构体内，根据所占bit数可以动态调整各自所占比特数.Step 3: Fill the obtained bufferId and bufferLength into the IPC message structure, and dynamically adjust the number of bits occupied by each according to the number of occupied bits.
步骤4，接收端收到IPC消息，提取bufferId、bufferLength，根据步骤1中定义的参数，根据公式BufferAddr = bufferId*UnitSize+ BaseAddr，确定buffer地址。Step 4, the receiving end receives the IPC message, extracts bufferId and bufferLength, and determines the buffer address according to the parameters defined in step 1 and the formula BufferAddr = bufferId*UnitSize+ BaseAddr.
步骤5，得出BufferAddr后，可对BufferAddr进行参数检查，判断其是否在合法范围内，合法则直接使用 BufferAddr并释放IPC消息，不合法，则返回异常并释放IPC消息。Step 5: After getting the BufferAddr, you can check the parameters of the BufferAddr to determine whether it is within the legal range. If it is legal, use the BufferAddr directly and release the IPC message. If it is not legal, return an exception and release the IPC message.
通过本可选示例，通过在处理bufferAddr时增加简单的计算，可以实现对bufferAddr的重构，重构后的每个bufferAddr所占bits减小，进而减小了IPC消息长度，相较于传输直接地址的方式，减小了非必要的传输，有效提升了带宽利用率，更高效、充分地利用了传输总线。Through this optional example, by adding simple calculations when processing bufferAddr, the reconstruction of bufferAddr can be realized. The bits occupied by each bufferAddr after reconstruction are reduced, thereby reducing the length of IPC messages. Compared with the method of transmitting direct addresses, unnecessary transmission is reduced, bandwidth utilization is effectively improved, and the transmission bus is more efficiently and fully utilized.
