Highly Efficient Flexible-Purging Redundancy Scheme

[[abstract]]A fault-tolerance technique for flexible-purging redundancy is proposed and designed. The sequence of purging the fault modules is set by 0, 1, 0,... alternately. The flexible-purging redundancy (FPR) scheme with N channels can tolerate N - 1 module failures in an optimal condition, as compared with an NMR configuration yielding (N - l)/2 module failures. Under the worst conditions, the FPR scheme still works properly and its reliability will not fall below the NMR configuration when two or more modules fail simultaneously. Elementary switches with voters are simple mechanisms. The complex circuit of the threshold unit for standby redundancy configuration is not required. FPR is easy to implement and is an efficient redundancy scheme for highly reliable systems.[[fileno]]2030129010007[[department]]電機工程學
