Abstract

PURPOSE:To diagnose the duplicated registers without stopping the working of a processor by providing an exchange control circuit between both registers so that the data on one of both registers to the other when the diagnosis is through with the former register and at the same time the working data is transferred to one of both registers. CONSTITUTION:An exchange control circuit 19 is provided between the duplicated registers 11 and 12 and actuated by a monitor device 13. The parity errors of both registers 11 and 12 are detected by the detecting circuits 14 and 15 and informed to the device 13. Then the data on the register 12 is transferred to the register 11 when the diagnosis is through with the register 12 and at the same time the working data on the register 11 is transferred to the register 12. Then a processor is actuated hereafter.
