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
