PURPOSE:To prevent a system from shutting off when a memory error is fixedly generated during the execution of a restart processing program on a singlet central processing system such as an exchange. CONSTITUTION:A memory error measurement counter 5, an OR circuit 6 inputting the OR output between a power-on reset signal and a multimemory error signal to a flip-flop 3, and an OR circuit 7 to be inputted to a restart control part 2 are provided on a fault processing part, and the memory error measurement counter 5 is counter up while using the memory error generation signal to be detected every time a memory error is generated as a clock. By a multimemory error signal to be outputted when the constant number of times of memory errors are generated, turning on a restart register and starting a start control part 2 are notified. By receiving this multimemory error signal, the start control part 2 recognizes that the power on bit is turned on, thereby executing the restart procedure at the time of turning on power supply. |
