Title:
ONLINE PARALLEL PROCESSING SOFT ERROR REAL-TIME ERROR DETECTION AND RECOVERY METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/037022
Kind Code:
A1
Abstract:
An online parallel processing soft error real-time error detection and recovery method and system. The method comprising: dividing a protected RAM space into multiple protected areas; dividing all of the protected areas into one or more levels, the highest level being to complete an error detection and recovery function in each interrupt cycle, and the other levels being to complete an error detection and recovery function once in multiple interrupt cycles; registering the protected areas of each level to generate a linked list corresponding to the number of levels, and backing up at least two copies of each linked list and the protected areas in the linked list to other RAM space; and processing in parallel the error detection and recovery of each level of linked list and each protected area in the linked list. The described solution can, in a key scenario, achieve the verification, decision, correction, and recovery of high-importance level data in a control system within a single interruption beat, and at the same time, does not rely on a CPU processor itself, can process in real-time in parallel, and can achieve an online real-time error detection and correction function when multiple positions of the CPU processor and a RAM are abnormally shifted at the same time.
