Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0079] It should be noted that, although the terms "first", "second", etc. are used to describe various information in the embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. Optionally, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0080] It should be understood that the terms "comprises" and "includes" indicate the presence of the previously mentioned features, steps, operations, but do not exclude the presence, occurrence or addition of one or at least one other feature, step, operation. The terms "and / or" and the like used in this application may be interpreted as inclusive, or mean any one or any combination. Optionally, "A and / or B" means "any of the following: A; B; A and B". In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship.

[0081] In the related art, a read-only memory (ROM) is a solid-state semiconductor memory that can only read out previously stored data.

[0082] ROM code can be stored in ROM. Once written into ROM, it can only be read out under normal working conditions and cannot be modified or deleted. ROM code can be used to implement functions such as CPU core initialization, boot program storage device interface initialization, loading secondary program loader (SPL) or file download loader (FDL). Since there may be errors and omissions when making ROM, or manufacturers intentionally modify ROM code to meet changing market needs, etc., it is necessary to repair the ROM code that has been solidified on ROM.

[0083] In the above case, the ROM can only be subjected to secondary wafer manufacturing, resulting in low repair efficiency.

[0084] In order to solve the above technical problems, the embodiment of the present application provides a data repair method, which enables the repair address in the ROM, calls the repair code on the random access memory (RAM) through the enabled repair address, and repairs the data in the ROM according to the repair code. In this way, when there are errors or omissions in the ROM, or the ROM code is intentionally modified, the ROM can be repaired without secondary wafer manufacturing. By running the repair code on the RAM, any instructions and logical functions are executed to repair the data in the ROM, so as to improve the repair efficiency.

[0085] Next, combine Figure 1 , the application scenarios of data repair are illustrated with examples.

[0086] Figure 1 This is a schematic diagram of an application scenario provided by the embodiment of this application. Figure 1 , Figure 1 The system may include a terminal device 100 , which may include a central processing unit 101 , a read-only memory 102 , and a random access memory 103 .

[0087] The CPU 101 can work in conjunction with the ROM 102 and the RAM 103 to complete various computing tasks.

[0088] The CPU 101 can read instructions from the ROM 102 or the RAM 103 and perform data processing and control operations according to the instructions.

[0089] The read-only memory 102 can be used to store fixed programs or data.

[0090] For example, the read-only memory 102 can store the control program in the embedded system to ensure that it will not be accidentally modified during the operation of the system. The central processing unit 101 can read the control program from the read-only memory 102 as needed to perform a specific task.

[0091] The random access memory 103 can be used to provide temporary storage space for programs and data in computer operation. When the computer runs a program, the program and data can be loaded into the random access memory 103 from a storage device such as a hard disk.

[0092] The CPU 101 can quickly read instructions and data from the RAM 103 and process them. During the execution of the program, the intermediate results and temporary data generated can also be stored in the RAM 103.

[0093] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0096] The current address is the address currently read by the CPU.

[0097] Device initialization codes can be stored in multiple addresses of the read-only memory ROM. When the device is started, the initialization codes in the ROM can be run. When the initialization codes in the ROM are run, the current address to which the central processor runs can be determined.

[0098] S202: Determine whether the current address is a repair-enabled address.

[0099] The enabling repair address may be a repair address after successful enabling.

[0100] The repair address can be used to repair the address of the code in the ROM.

[0101] The enabling success can be used to indicate that the repair code corresponding to the repair address is allowed to run.

[0102] At least one enabled repair address may be obtained, and it may be determined whether the current address exists in the at least one enabled repair address. If so, it may be determined that the current address is the enabled repair address; if not, it may be determined that the current address is not the enabled repair address.

[0106] Optionally, when the current address is a repair-enabled address, a code corresponding to the current address may be determined according to the current address, and a target address for repair may be determined in a random access memory RAM through the code.

[0107] For example, assuming that the current address is the enable repair address, the current address is 0x21000010, and the corresponding target address is 0x00000000 in the RAM.

[0108] When the CPU runs to address 0x21000010, it can be determined that the address is the enable repair address, and the code in 0x21000010 is run. After the code execution is completed, it can be determined that the target address is 0x00000000 in RAM.

[0109] Optionally, the corresponding target address can be determined in the random access memory RAM according to the current address in the following manner: determine the first code in the ROM according to the current address; run the first code to call the protection field program in the ROM corresponding to the first address; and determine the corresponding target address in the random access memory RAM through the protection field program.

[0110] The first code includes a first address in the ROM.

[0111] The saved on-site program may be an executable code solidified in ROM.

[0112] The execution code may be used to store current operation information. For example, the current operation information may be related general register information and the like.

[0113] It should be noted that the target address for repair can be determined in the random access memory RAM according to the current address through any feasible implementation method, and the embodiment of the present application is not limited to this.

[0114] S204: Determine a repair code in the RAM according to the target address, and repair the data in the ROM according to the repair code.

[0115] The repair code can be stored in the space corresponding to the target address.

[0116] The repair code can perform specific instructions and logic functions to fix the vulnerability in the ROM.

[0117] For example, the repair code may change configuration information in a register, etc., and the functions that the repair code may implement are not limited herein.

[0118] The repair code can be determined in the RAM according to the target address, and the repair code can be run to execute specific instructions and logic functions to repair the data in the ROM.

[0119] The data repair method provided in this embodiment determines the current address in the ROM, determines whether the current address is an enabled repair address, and if so, determines the target address for repair in the random access memory RAM according to the current address, determines the repair code in the RAM according to the target address, and repairs the data in the ROM according to the repair code. In this way, when there are errors or omissions in the ROM, or the ROM code is intentionally modified, the ROM can be repaired without secondary wafer manufacturing, and the data in the ROM can be repaired by running the repair code on the RAM to execute any instructions and logical functions, so as to improve the repair efficiency.

[0128] When the current address is the repair-enable address, the current address may be read to determine the storage space in the ROM, and the first code may be obtained from the storage space.

[0129] S304: Run the first code to call the protection field program corresponding to the first address in the ROM.
