摘　　要：计算机处理器的可靠性设计非常重要.设计了三值光学处理器(ternary optical processor,TOP)三模冗余(triple module redundancy,TMR)光电表决系统,针对三值光学处理器运算单元设计了光电表决器,提出了在三值光学处理器上构建表决系统架构的具体步骤.对于一位的三值光学处理器,设计并测试了108个表决实验用例,并对m位的重构运算器的可靠性进行了简要分析.实验结果与可靠性分析表明,针对三值光学处理器进行三模冗余表决的方案,能有效提高系统的可靠性及运行效率.Reliability in the design of computer processor is essential. This paper focuse on designing a triple module redundancy (TMR) photoelectric voting system for the ternary optical processor (TOP). The photoelectric voters for TOP process units are presented. Steps for implementing the voting framework are illustrated. A voting experiment for TOP of 1-bit is carried out, where 108 voting examples are designed and executed. A reliability analysis of m-bit reconfigured operators is briefly discussed. Experimental results and reliability analysis show that the TMR voting scheme for TOP can improve operating efficiency and reliability of the system.
