摘要： A dual computer system comprising a pair of processor units, and a dual control unit for controlling which of the two processor units are to be kept operating or on standby in case of failure of the operated unit; wherein the dual control unit controls which processor unit is to be operated through monitoring of the operating states of the two processor units, and comprising two independent interruption devices for indicating the switching of the two processor units through interruption. The system is effective in improving the continuity of the control at the time of switching.
