摘要
n -模块化冗余(NMR)的变体允许NMR系统在保持相同可靠性模型的情况下具有高达两倍的吞吐量。每个任务由大多数处理器执行。对任务进行诊断(通过比较它们的结果)，而不是对处理器进行诊断(通过单独的诊断过程)。这种方案不会增加电路的复杂性，因为诊断不必是自适应的。可以容忍间歇性和瞬态以及永久性故障。
Efficient NMRCD scheme for fault tolerance in responsive systems
A variant of N-Modular Redundancy (NMR) allows an NMR system to have up to twice the throughput while keeping the same reliability model. Each task is executed by a majority of processors. The tasks are diagnosed (by comparing their results) rather than the processors (by a separate diagnostic process). This scheme does not increase the complexity of the circuitry involved as diagnosis does not have to be adaptive. Intermittent and transient, as well as permanent faults are tolerated.
