확장 ASR 기법을 이용한 임무지향 컴퓨터의 설계 및 신뢰도 분석

Abstract

ABSTRACT The mission-critical computer for air defense has to maintain its operation without any fault for a long mission time and is required to implement at low cost. Now the reliability of the mission critical-computer using Active Sparing Redundancy fault-tolerant technique is inferior to that of the computer using TMR technique. So in this paper are proposed Extended ASR(EASR) technique that provides higher reliability than that of the computer using TMR technique. The fault-tolerant performance of the implemented mission-critical computer is proven through reliability analysis and numbers of fault recovery test. Also, the reliability of the mission-critical computer using EASR technique is compared with those of computer using ASR and TMR techniques. EASR technique is very suitable to the mission-critical computer.Keywords:Active Sparing Redundancy, Extended Active Sparing Redundancy, Fault Tolerant, Fault Detection, Fault Recovery, Mission-Critical Computer, Mission Reliability
