Firmware hot upgrade refers to an upgrade method that does not interrupt the execution of the original program during the upgrade process. Since the firmware hot upgrade will not interrupt the execution of the original program, which brings great convenience to the firmware upgrade, the firmware hot upgrade is of great significance in the firmware upgrade. The firmware upgrade method provided in this specification will be described below with reference to specific embodiments.
图1本说明书实施例提供一种固件升级方法的示意图。如图1所示，固件升级方法包括如下步骤：FIG. 1 is a schematic diagram of a firmware upgrade method provided by an embodiment of the present specification. As shown in Figure 1, the firmware upgrade method includes the following steps:
步骤S101：获取拟升级固件的固件升级请求，所述固件升级请求携带有固件升级程序。Step S101: Obtain a firmware upgrade request for firmware to be upgraded, where the firmware upgrade request carries a firmware upgrade program.
固件是一种与硬件紧密结合并集成一体的程序逻辑，是一种重要的硬件服务。在本说明书实施例中，所述拟升级固件至少包括第一存储区和第二存储区，所述第一存储区包括程序区和标志区，所述第二存储区包括数据区和命令缓冲区。Firmware is a program logic that is closely integrated with hardware and is an important hardware service. In the embodiment of this specification, the firmware to be upgraded includes at least a first storage area and a second storage area, the first storage area includes a program area and a flag area, and the second storage area includes a data area and a command buffer area .

图2为本说明书实施例提供的一种拟升级固件的结构图。如图2所示，该固件由第一存储区和第二存储区两个存储区构成，其中，第一存储区包括：程序区和标志区，第二存储区包括：数据区和命令缓冲区。FIG. 2 is a structural diagram of a firmware to be upgraded according to an embodiment of the present specification. As shown in Figure 2, the firmware is composed of two storage areas: a first storage area and a second storage area, wherein the first storage area includes: a program area and a flag area, and the second storage area includes: a data area and a command buffer area .
程序区的个数至少为两个，为便于说明，下面将以程序区包括两个可编译的程序区予以说明。需要特别说明的是，程序区的个数可以根据业务需求而定。The number of program areas is at least two. For the convenience of description, the following will describe the program area including two compilable program areas. It should be noted that the number of program areas can be determined according to business requirements.
第一种情况，第一存储区所包括的程序区均为可编译的程序区，为便于说明，命名为程序A区和程序B区。则进行固件版本编译时，分别根据程序A区和程序B区的起始地址，将固件编译成两个独立的版本程序，分别命名为F-A和F-B，固件可以从程序A区和程序B区独立执行。In the first case, the program areas included in the first storage area are all compilable program areas, and are named as program A area and program B area for convenience of description.

The firmware can be independent from the program A area and the program B area. implement.
第二种情况，第一存储区所包括的程序区除了包括可编译的程序区，还包括一个不可更改的程序区，为便于说明，命名为程序0区，程序A区和程序B区，其中，程序0区为不可更改的程序区，程序A区和程序B区为可编译的程序区。则进行固件版本编译时，分别根据程序0区、程序A区和程序B区的起始地址，将固件编译成三个独立的版本程序，分别命名为F-0、F-A和F-B，固件可以从程序A区和程序B区独立执行，而程序0区是不可以进行任何修改的，相当于固件默认的程序。进一步通过带外的方法，将F-A写入程序A区，同样，通过带外的方法，把标志区的内容写为A。将F-B写入程序B区，标志区的内容为B。带外即带外管理，是指管理控制信息与数据信息使用不同的物理通道进行传送。关于带外方式的具体内容，在此不再进行赘述。In the second case, the program area included in the first storage area not only includes the compilable program area, but also includes an unchangeable program area. , the program 0 area is the unchangeable program area, and the program A area and the program B area are the compilable program areas. When the firmware version is compiled, the firmware is compiled into three independent version programs according to the starting addresses of the program 0 area, the program A area and the program B area, respectively named as F-0, F-A and F-B. The program A area and the program B area are executed independently, and the program 0 area cannot be modified in any way, which is equivalent to the default program of the firmware. Further through the out-of-band method, F-A is written into the program A area, and similarly, through the out-of-band method, the content of the flag area is written as A. Write F-B into the program B area, and the content of the flag area is B. Out-of-band or out-of-band management means that management control information and data information are transmitted using different physical channels. The specific content of the out-of-band mode will not be repeated here.

为便于理解，继续延续前例，予以说明。如前所述，针对第一种情况，第一存储区所包括的程序区均为可编译的程序区时，标志区的内容可以为A或B，程序A对应的固件为F-A，程序B对应的固件为F-B，预设的升级策略为，当标志区内容为A时，将程序A对应的固件F-B发送到命令缓冲区；当标志区内容为B时，将程序B对应的固件F-A发送到命令缓冲区。针对第二种情况，第一存储区所包括的程序区除了包括可编译的程序区，还包括一个不可更改的程序区时，标志区的内容可以为0、A或B，程序0对应的固件为F-0，程序A对应的固件为F-A，程序B对应的固件为F-B，预设的升级策略为，当标志区内容为0时，将程序0对应的固件F-A发送到命令缓冲区，当标志区内容为A时，将程序A对应的固件F-B发送到命令缓冲区；当标志区内容为B时，将程序B对应的固件F-A发送到命令缓冲区。For ease of understanding, the previous example is continued and explained. As mentioned above, for the first case, when the program areas included in the first storage area are all compilable program areas, the content of the flag area can be A or B, the firmware corresponding to program A is F-A, and program B corresponds to The firmware is F-B, and the preset upgrade strategy is, when the content of the flag area is A, send the firmware F-B corresponding to program A to the command buffer; when the content of the flag area is B, send the firmware F-A corresponding to program B to the command buffer. command buffer. For the second case, when the program area included in the first storage area includes an unchangeable program area in addition to a compilable program area, the content of the flag area can be 0, A or B, and the firmware corresponding to program 0 is F-0, the firmware corresponding to program A is F-A, and the firmware corresponding to program B is F-B. The preset upgrade strategy is that when the content of the flag area is 0, the firmware F-A corresponding to program 0 is sent to the command buffer. When the content of the flag area is A, send the firmware F-B corresponding to program A to the command buffer; when the content of the flag area is B, send the firmware F-A corresponding to program B to the command buffer.

本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于装置、电子设备、非易失性计算机存储介质实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。Each embodiment in this specification is described in a progressive manner, and the same and similar parts between the various embodiments may be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the apparatus, electronic equipment, and non-volatile computer storage medium embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and reference may be made to some descriptions of the method embodiments for related parts.
本说明书实施例提供的装置、电子设备、非易失性计算机存储介质与方法是对应的，因此，装置、电子设备、非易失性计算机存储介质也具有与对应方法类似的有益技术效果，由于上面已经对方法的有益技术效果进行了详细说明，因此，这里不再赘述对应装置、电子设备、非易失性计算机存储介质的有益技术效果。The apparatuses, electronic devices, and non-volatile computer storage media provided in the embodiments of this specification correspond to the methods. Therefore, the apparatuses, electronic devices, and non-volatile computer storage media also have beneficial technical effects similar to those of the corresponding methods. The beneficial technical effects of the method have been described in detail above, and therefore, the beneficial technical effects of the corresponding apparatus, electronic equipment, and non-volatile computer storage medium will not be repeated here.
在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable GateArray，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware DescriptionLanguage)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(RubyHardware Description Language)等，目前最普遍使用的是VHDL(Very-High-SpeedIntegrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。In the 1990s, improvements in a technology could be clearly differentiated between improvements in hardware (eg, improvements to circuit structures such as diodes, transistors, switches, etc.) or improvements in software (improvements in method flow). However, with the development of technology, the improvement of many methods and processes today can be regarded as a direct improvement of the hardware circuit structure. Designers almost get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware entity modules. For example, a Programmable Logic Device (PLD) (eg, Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. It is programmed by the designer to "integrate" a digital system on a PLD without having to ask the chip manufacturer to design and manufacture a dedicated integrated circuit chip. And, instead of making integrated circuit chips by hand, these days, much of this programming is done using software called a "logic compiler", which is similar to the software compiler used in program development and writing, but before compiling The original code also has to be written in a specific programming language, which is called Hardware Description Language (HDL), and there is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (RubyHardware Description Language), etc. The most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that a hardware circuit for implementing the logic method process can be easily obtained by simply programming the method process in the above-mentioned several hardware description languages and programming it into the integrated circuit.
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。The controller may be implemented in any suitable manner, for example, the controller may take the form of eg a microprocessor or processor and a computer readable medium storing computer readable program code (eg software or firmware) executable by the (micro)processor , logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers and embedded microcontrollers, examples of controllers include but are not limited to the following microcontrollers: ARC625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicon Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer-readable program code, the controller can be implemented as logic gates, switches, application-specific integrated circuits, programmable logic controllers and embedded devices by logically programming the method steps. The same function can be realized in the form of a microcontroller, etc. Therefore, such a controller can be regarded as a hardware component, and the devices included therein for realizing various functions can also be regarded as a structure within the hardware component. Or even, the means for implementing various functions can be regarded as both a software module implementing a method and a structure within a hardware component.
