AI Technical Summary

Technical Problem

Existing ECC memory verification cannot effectively protect against multi-bit errors in environments with strong electromagnetic interference, resulting in high false negative rates and untimely data recovery. Furthermore, the complex ECC algorithm consumes a large amount of CPU resources and cannot meet real-time requirements.

Method used

By periodically polling the power management chip's ripple voltage, the memory controller bus's eye width, and the DRAM's memory temperature, the system compares these data in real time and triggers bit error repair and memory frequency reduction operations. It employs a hierarchical error repair mechanism, including automatic hardware single-bit error flipping, DRAM hardware reserved area backup pages, and memory snapshot processes, to achieve proactive protection.

Benefits of technology

It achieves proactive protection of memory data under strong electromagnetic interference, improves system stability and data integrity, reduces the occurrence rate of multi-bit errors, avoids system crashes, and meets the business requirements of real-time performance and high reliability.

Abstract

The application relates to the technical field of data processing, and particularly provides a memory data processing method and device for an operating system under strong electromagnetic interference, wherein the ripple voltage of a power management chip, the bus eye width of a memory controller bus and the memory temperature of DRAM are periodically polled; in each polling cycle, the ripple voltage, the bus eye width and the memory temperature are compared with a preset threshold set, and if any parameter exceeds the threshold, a bit error repair operation and a temporary memory frequency reduction operation are synchronously triggered; through parameter polling and hierarchical error repair, active protection of memory data under strong electromagnetic interference is realized. By adopting an adaptive polling cycle, the power ripple, the bus eye width and the DRAM temperature are collected in real time, error repair and memory frequency reduction are synchronously started, interference diffusion is blocked, the success rate of atomic page replacement repair is improved, the system stability is improved under a strong electromagnetic environment, and the problem of guaranteeing the integrity of memory data under extreme interference is effectively solved.
