摘要： 木文介绍了FACOM M340中大型计算机系统设计中采用的RAS技术。对CPU重试,通道重试,存储器纠错等自动错误恢复技术的实现与性能作了详细的分析。提示了中大型系统中自动错误记录系统与自动故障恢复体系的概念,以及现代采用LSI系统中提高RAS性能设计上的考虑。

Abstract: This article is intended to explain the RAS technique in FACOM M 340 computer system. Detailed analysis and explanation have been made on automatic fault recovery, such as, CPU retry, channel retry, and memory error correction. Auto-error-recording system and auto-error-recovery hierarchy in medium-large scale systems are conceptualized. Some RAS considerations on the system consisting of LSIs are covered.
