Memory detection method and device

Abstract

The invention discloses a memory detection method. The verification method comprises: in a bypass mode, extracting first data from the data to be input into the memory according to a predetermined extraction rule, and passing a CRC verification algorithm with a predetermined number of digits Calculate the extracted first data to obtain the first check code; in the bypass mode, extract the second data from the data to be output to the memory according to the predetermined extraction rules, and use the CRC check algorithm of the predetermined number of digits to check the code The extracted data is calculated to obtain a second check code; the first check code is compared with the second check code, and the working condition of the memory is determined according to the comparison result. The present invention detects the memory in real time in the bypass mode, which can avoid the impact on the data processing on the main line during the memory detection process, and does not affect the system performance; Test processing, increase the accuracy of memory detection, and find problems in the memory in a timely manner.

Description

technical field [0001] The invention relates to the field of computers, in particular to a memory detection method and device. Background technique [0002] With the development of network technology, the amount of information that needs to be detected and processed in the network is increasing. Therefore, the use of large-capacity data memory has become an inevitable trend. In the field of network security, due to the sensitivity of network security equipment to data content, the normal operation of memory chips directly affects the subsequent detection and processing of data. That is to say, the detection of memory is very necessary and urgent at present. [0003] For errors in memory, according to the cause of the error, it can be divided into hard errors and soft errors. Among them, hard errors are caused by hardware damage or defects, so the data caused by hard errors is not correct. Corrected; for soft errors, which appear randomly, for example, when interference fact...
