AI Technical Summary

Technical Problem

Before using random numbers as error-recall data for error correction processing, existing data error correction verification methods need to determine whether the random number is consistent with the previous data, resulting in complex processes and low efficiency, and judgment based on the flag bits returned by the memory controller, which has poor reliability.

Method used

By obtaining the original backup data, it is determined to be multi-bit or single-bit data, and input it into the simulation error-note model for error-note processing. For multi-bit data, the error-repellent processing is performed on high and low bit data in parallel, and the error-repellent data is obtained and inputted to the target memory controller for error-correction processing, return the error-correction data and flag bit information, and perform two-factor verification to improve reliability.

Benefits of technology

The data error correction verification process is simplified, processing efficiency is improved, the problem of repeated mistakes is avoided, and the reliability of error correction verification is improved through two-factor verification.

Abstract

The invention relates to a data error correction verification method and device, equipment, a medium and a program product. The data error correction verification method comprises the following steps: acquiring original backup data, and determining whether the original backup data is multi-bit backup data or single-bit backup data; when it is determined that the original backup data is multi-bit backup data, high-bit data and low-bit data in the original backup data are determined, a multi-bit error injection data generation module in the simulation error injection model is called, and error injection processing is conducted on the high-bit data and the low-bit data in a parallel mode; performing error correction processing on the first error injection data by the target memory controller; and performing error correction verification processing on the basis of the error correction data and the flag bit information returned by the target memory controller, so that the error injection processing of the data can be performed through the simulation error injection model, the data error correction verification process is simplified, the processing efficiency is improved, meanwhile, dual verification is performed through the error correction data and the flag bit information returned by the controller, and the error correction verification efficiency is improved. And the reliability of error correction verification is improved.
