摘要
研究总结了总线上的实时非干预可再现同步故障注入模式,并给出了它的具体实现。研究基础是针对目前国内应用比较广泛的以Intel 8086／80186、386EX、51系列兼容单片机为MPU／MCU的高可靠目标系统,是该类目标系统软件实时仿真测试环境的一个重要组成部分。测试过程将不影响目标系统的实时性能和功能,并可实现测试过程的行为再现。它的实现利用了现代微机的高性能、多任务多线程以及FPGA、PCI等技术。作为故障注入模式的一种,其具有新颖性和重要的实用价值。
The on-bus real-time synchronization fault injection way with noninterference and replay mechanism is studied and its realization is presented. The research is based on the target systems with the MPU/MCU of Intel 8086/80186, 386 EX, the series compatible with MCS-51products etc, which are widely used in our country, and is the important components of the target system software' realtime testing environment with emulating. The testing course won't interfere with the real-time performance and function of the target systems and can be replayed. It takes the advantage of high capabilities, multi-processes and multithreads in modern microcomputers and uses the technologies, such as PCI, FPGA etc. There are novelty and important use value as a fault injection way.
