Title:
METHOD AND SYSTEM FOR DETECTING AND RECOVERING MEMORY BIT FLIPPING IN SECONDARY POWER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2021/208341
Kind Code:
A1
Abstract:
A method and system for detecting and recovering memory bit flipping in secondary power equipment, related to the technical field of memory error correction. The technical problem to be solved is equipment malfunctioning or result abnormality caused by memory bit flipping in secondary power equipment in the prior art. The method comprises the following steps: performing an ECC verification code calculation according to a preset ECC segment length with respect to an application running area when an application is loading, acquiring an ECC verification code for segment data of the application when the application is loading; performing an ECC verification code calculation according to the preset ECC segment length with respect to the segment data of the application when the application is running, acquiring an ECC check code for the segment data of the application when the application is running; comparing the ECC verification code with the ECC check code; and, if the segment data of the application when the application is running is determined, on the basis of the comparison result, to have experienced a single bit error, correcting the bit where the error occurred.
