本文总结用于航天机载处理的容错计祘方面长期研究的结果。随着器件工艺的改变,研制方案已从容错单处理机的设计进展到容错分佈计祘机系统的研制,航天计祘的特殊要求与引起的实时计祘机系统结构结果一起进行介绍,並对设计的下列各方面进行讨论:1>简化分佈计祘机系统复杂性的系统结构的特奌。2>故障检测和恢复。3>提高可靠性和可测试性的技术。4>用LSI的设计方法。 This paper summarizes the results of long-term research on fault-tolerant gauges for aerospace onboard processing. With the change of device technology, the development scheme has been introduced from the design progress of fault-tolerant single-processor to the fault-tolerant distribution system. The special requirements of aerospace measurement system are introduced together with the real-time system architecture results. The following aspects of the design are discussed: 1> Features that simplify the system architecture for distributing system complexity. 2> fault detection and recovery. 3> Techniques to improve reliability and testability. 4> LSI design method.
