Abstract

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.

Key words： ternary optical processor (TOP); triple module redundancy (TMR); voter design; reliability
