ABSTRACT:
A highly reliable computer system is intended to duplicate processors, compare the outputs of the processors with each other and enhance the validity of the output of processor system. If a mismatch between the outputs is detected, one of the processors performs a process of saving an internal state of the processor in amain memory and diagnosing factor of the detected mismatch. If the process is recognized to be continued in a duplex mode, the processors are re-synchronized by a processor reset, and initialize themselves and restore the internal information saved in the main memory for continuing the process having been proceeded before the fault occurred.
