| 摘 要： | 本文讨论在实时控制系统中以高可靠性为目的,实施Z80 PIO上一种容错方案,即带汉明校验的双PIO方案。其中一个PIO处于热待命状态随时准备接替出错的工作模块。通过可靠率分析和实践证明,这是一种行之有效的方案。

| Abstract: | This paper discusses a fault-tolerant structure which is implimented on a Z80 PIO for the purpose of high reliability in a real-time control system. It is a structure of double PIO's with Hamming check code. One of the two PIO's is in a heat armed state and is prepared to replace a failure working module at any time. This structure proves to be practical and effective in the real-time control system combining an armed system with Hamming check code. |
