초록

This paper shows two models of the TMR system- fail passive system - having a fault tolerant system characteristic used in airplane and railway system. We design the single system, single-voter TMR system and triplicated voter TMR system based on MC68000 and calculate the failure rate of components using MIL-SPEC-217F and evaluate the reliability and MTTF(Mean Time To Failure) of the designed systems by Markov model.
