通用容错测试仪GFTE的设计与实现

Design and Implementation of Fault-tolerant Evaluation Tool GFTE

故障注入是一种有效的测试和评价容错机制的方法 ,可被普遍应用于容错计算机系统开发的各个阶段中。本文提出了一种基于嵌入式故障注入的容错设备测试方案 ,称之为GFTE ,是针对以 80 4 86 ,80 386 ,80 86为处理器的容错计算机系统设计的。文中详细讨论了GFTE的三个组成部分 :测控模块、通用管理模块和注入器的设计 。

Fault injection is a powerful method for test and evaluation of fault-tolerance mechanisms, which may be widely used during all phases of developing of fault-tolerant computer systems. In this paper a scheme of evaluating fault-tolerant mechanisms for general purpose, called GFTE, is proposed. It is designed for fault-tolerant systems based on 80486, 80386 and 8086.GFTE consists of three parts, including test and control module, general management module and injection design.The design and implement of these three parts are discussed in detail.
