本文介绍某大型通用数字计算机的可靠性逻辑设计。为了提高计算机的可靠性、可利用性和可维修性,在体系设计方面考虑了一个较为完整的故障检查系统,其主要措施是(ⅰ)主存采用错误校正码:能校正一位错,检测两位错和部分多位错。(ⅱ)主机(运控、指控、存控)奇偶预测检查:对信息流进行闭环的检查,查出故障后进入中断程序自动恢复处理。(ⅲ)主机故障定位诊断:主机设有诊断部件,可执行诊断程序,对主机进行故障定位诊断。
This article describes the reliability of a large general-purpose digital computer logic design. In order to improve the reliability, availability and maintainability of the computer, a more complete fault checking system is considered in the system design. The main measures are as follows: (i) The main memory adopts the error correcting code, which can correct a bit error, detect Two mistakes and some mistakes. (Ii) The host (operation and control, accusation, control) parity prediction check: the flow of information on the closed-loop checks to identify the fault into the interrupt process automatically resume processing. (Iii) Host fault diagnosis: The host is equipped with diagnostic components that can execute diagnostics to diagnose faults on the host.
