摘　　要：研究了在三值光学计算机(ternary optical computer,TOC)的解码结果发送和接收部件之间建立通信子系统的问题.建立了数据重发机制和通信系统重启机制,并利用这两个机制来分别提高对通信系统本身以及对周边器件的偶发瞬态故障的容忍能力,还利用附加的标示信息实现了对数据线路发生永久性故障的判定能力.将这些技术结合内部集成电路(inter-integrated circuit,IIC)通信方式,实现了一个用于TOC解码器的实用通信系统,并对这个系统的整体性能进行了详细测试.讨论了对所完成系统的实验研究,包括实验内容的选取、实验软件的设计、测试用例的设置和实验过程等.大量的实验结果证明了该通信子系统的科学性和可靠性.This paper proposes a method of establishing a communication subsystem between a decoder and other units in a ternary optical computer（TOC）. Mechanisms of repeatedly sending data and restarting the communication system are used to improve fault-tolerant ability against occasional transient faults of the system and the peripheral devices. Additional identification information is used to detect permanent failures of the communication link. Combining these techniques with inter-integrated circuit（IIC）, a practical communication system for TOC decoders is completed. The overall performance of the system is tested in details. Selection of experimental contents, design of experimental software, settings of test cases and the experimental process are discussed. The experimental results show effectiveness and reliability of the communication subsystem.
