개선된 전방복구기법을 적용한 시간제약 결함허용시스템의 최적화

초록

Unnecessary double check and scattered usage of spare processor in Forward Recovery Technique cause longer overall operation time. In this paper, we propose a new operational scheme, Improved-Forward Recovery Technique, which uses the spare processor in Forward Recovery Technique as a check-only processor, to reduces execution time and operates in another way when error has been detected. We have verified improved performance and reduced execution time.
