The method embodiments provided in the present embodiment may be executed in a terminal, a computer, or a similar computing device. For example, the method is executed on a terminal, and fig. 1 is a block diagram of a hardware structure of the terminal according to the method for updating a memory partition in this embodiment. As shown in fig. 1, the terminal may include one or more processors 102 (only one shown in fig. 1) and amemory 104 for storing data, wherein theprocessor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA. The terminal may also include atransmission device 106 for communication functions and an input-output device 108. It will be understood by those of ordinary skill in the art that the structure shown in fig. 1 is merely an illustration and is not intended to limit the structure of the terminal described above. For example, the terminal may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.
Thememory 104 may be used to store computer programs, for example, software programs and modules of application software, such as a computer program corresponding to the method for updating the memory partition in the embodiment, and theprocessor 102 executes various functional applications and data processing by running the computer programs stored in thememory 104, so as to implement the method described above. Thememory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, thememory 104 may further include memory located remotely from theprocessor 102, which may be connected to the terminal over a network.

In one example, thetransmission device 106 may be a Radio Frequency (RF) module, which is used to communicate with the internet in a wireless manner.
In the updating process of the computer system software, because the files of the new version system software and the old version system software are not consistent, the memory space division region of the old version system software may not be matched with the new version system software, and therefore a new space division region needs to be established based on the new version system software. However, in the system updating process, the new space division region is a virtual division region, so that the address of the new space division region needs to be mapped to the address of the original space division region, and the related file of the new version of system software can be stored in the physical region of the memory.
However, since the space-dividing regions are independent from each other, two or more space-dividing regions cannot be mapped to the same space-dividing region, that is, a mapping relationship between a new space-dividing region and an original space-dividing region cannot be established across partitions. Therefore, a total space region needs to be established in the middle, and the new space division region and the original space division region both directly establish a mapping relationship with the total space region, thereby indirectly establishing a mapping relationship between the new space division region and the original space division region.

However, since the storage space of each first storage area is fixed and independent from each other, the corresponding relationship can only be established in the storage space range of the first storage area, that is, the address of the same first storage area cannot correspond to the addresses of two or more second storage areas, and thus the corresponding relationship between the address of the first storage area and the address of the second storage area cannot be established across partitions.
In one embodiment, as shown in fig. 6, the 3-partition 2 unit and the 4-partition 1 unit in the first storage area are bad blocks, and the 4-partition 1 unit of the second storage area should correspond to the 3-partition 2 unit of the first storage area in the case that there is no bad block. When a bad block exists in the 3-partition-2 unit of the first storage area, the next storage unit, namely the 3-partition-3 unit of the first storage area, needs to be acquired, and the address of the next storage unit corresponds to the 4-partition-1 unit of the second storage area.
In this embodiment, the storage unit addresses of the total storage area corresponding to each storage unit of each second storage area are sequentially acquired in the total storage area, and the storage unit addresses of the first storage areas corresponding to the storage unit of the total storage area are sequentially acquired in the plurality of first storage areas, so that the storage units of the first storage areas and the storage units of the second storage areas can establish a corresponding relationship across partitions, and when the storage unit of the first storage area needs to be accessed, the corresponding storage unit of the second storage area is directly acquired, thereby improving the access speed of the storage area partitions.
In another embodiment, establishing correspondence between the plurality of first memory area addresses and the plurality of second memory area addresses includes:
and establishing a mapping relation list of a plurality of first storage area addresses and a plurality of second storage area addresses.
Illustratively, a mapping relation list is established based on a plurality of first storage area addresses and a plurality of second storage area addresses, and the corresponding storage units of the first storage area can be quickly accessed through the mapping relation list based on the storage unit addresses of the second storage areas.
Illustratively, the mapping relationship list further includes a fast index channel for fast matching the address of the second storage area and mapping to the storage unit of the corresponding first storage area.
The embodiment establishes the mapping relation list of the first storage area address and the second storage area address, and when the first storage area needs to be accessed, the first storage area address and the second storage area address can be directly retrieved and mapped in the mapping relation list, so that the access convenience of the first storage area is improved, and the updating efficiency of the storage area partition is further improved.
In another embodiment, the sum of the storage spaces of the plurality of first storage areas is less than or equal to the storage space of the memory.
Illustratively, the sum of the storage spaces of the plurality of first storage areas may be the storage space of the whole memory, or may be only a part of the storage space of the memory. It will be appreciated that during an update of a memory partition, the total storage area need only be established for memory partitions that need to be updated across partitions, and need not be established for all partitions of memory.
Referring to fig. 7, in another embodiment, a system software updating method includes: acquiring the initial address and the storage space of a second storage area corresponding to each image file based on system software to be updated, and establishing the corresponding relation between the address of the first storage area and the address of the second storage area through a total storage area; calling a system upgrading interface, and transmitting the initial address of the second storage area, the image file of the system software to be updated and the size of the image file into the system upgrading interface; and acquiring the address of the second storage area address corresponding to the image file in the first storage area, namely the actual storage address, through the corresponding relation between the first storage area address and the second storage area address, and writing the image file into the actual storage address through a second storage area control unit.
It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
