一种快速可靠的串行flash容错系统的设计与实现

The Design and Implementation of a Fast and Reliable Fault-Tolerant System of Serial flash

在工业控制/实时控制系统中,常需要用串行E2PROM/flash来保存重要数据。文章先分析了串行flash的错误特征,并结合器件发展的实际,介绍一种实用的、快速的、可靠的串行flash容错系统的设计与实现方法,最后给出一个在单片机上实现的软件及容错系统性能分析。

We generally require some serial E2PROMs/flashes to store the important data in the industrial control systems or real-time systems. This paper first analyzes the error characteristics of the serial flashes,then presents thedesign and implementation of a practical,fast,reliable fault-tolerant system of serial flashes referring to the recent component development. Finally,it introduces a software of this system programming in a single chip process,and analyzes the system's performance.
