Abstract:SUMMARYEnhancement of fault recovery coverage by early discovery and early recovery is indispensable in enhancing the availability of fail-safe systems and fault-tolerant systems. In clock-synchronized duplicate comparison systems, errors can be detected in the clock unit, facilitating the early discovery and recovery of faults. Addition of optimal-time diversity makes possible the prevention of error correlation in the duplicate comparison systems, which promotes coverage enhancement. This paper presents an e… Show more
