Problems solved by technology

[0009] However, in the process of realizing the technical solution of the invention in the embodiment of the application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: when the electronic device has only one memory stick DIMM and the number of bits of each chip in the memory is 8 bits , since 512 bits of data are required to perform an ECC data verification, 8 reads and writes to the DIMM are required. It can be seen that there is a technical problem in the prior art that it takes a long time to complete an ECC data verification

Abstract

The invention discloses a data check method and device and electronic equipment. The method includes the steps that 256-bit data are obtained; 13-bit first checksum data related to the obtained data and generated according to a first checksum algorithm are obtained; the obtained data are subjected to checksum calculation according to the first checksum algorithm, and 13-bit second checksum data are generated; the first checksum data and the second checksum data are compared, and a comparison result is obtained; the correctness of the obtained 256-bit data is determined according to the comparison result.

Description

technical field [0001] The invention relates to data verification technology, in particular to a data verification method and device, and electronic equipment. Background technique [0002] Memory (Memory) is one of the important components in electronic equipment, and it is a bridge to communicate with the central processing unit (CPU) in the electronic equipment. The function of the memory is to temporarily store the calculation data in the CPU and the data exchanged with the external memory such as the hard disk. When electronic equipment is running, the CPU will transfer the data that needs to be calculated to the memory for calculation. After the calculation is completed, the CPU will transfer the result to the memory. The operation of the memory also determines the stable operation of the computer. [0003] Memory is an electronic device, and errors will inevitably occur during its working process. For users with high stability requirements, memory errors may cause fa...
