本文提出了一个计算机实现容错存储器的思想,主要解决计算机运行时存储器的瞬时错误,采用硬件检测错误,软件改正错误。 文中阐述了静态伴随纠错码(SFEC),动态伴随纠错码(DFEC)和“看门”寄存器的基本概念及实现方法。SFEC码与DFEC码之差就是正确码,因此计算机在运行中出现存储器故障时,仍能正确地执行程序组。 This paper presents a computer implementation of fault-tolerant memory idea, mainly to solve the computer run-time memory instantaneous error, the use of hardware detection errors, software correction errors. In this paper, the basic conceptions and implementation methods of SFEC, DFEC and Gatekeeper registers are described. The difference between the SFEC code and the DFEC code is the correct code, so the computer can still execute the program correctly when there is a memory failure during operation.
