Abstract:A triple modular redundancy (TMR) system incorporates majority voting to achieve fault tolerance, although not all single faults can be tolerated due to the possibility of voter failure. A totally self-checking (TSC) circuit is introduced to monitor the TMR system; it receives the outputs of each module and that of the voter to generate three system statuses, and three module status outputs. The TSC± TMR system has the capability to detect all single fault occurrences inclusive of the checking circuitry, thus … Show more
