Abstract

PURPOSE: To execute diagnosis in on-line without lowering of the processing efficiency, by utilizing the waiting time of the operation processing unit to diagnose the data processing unit continuously.
CONSTITUTION: The microinstruction of the prescribed number of bits read out from control memory part 11 where various microprograms are stored is held in microinstruction register 12, and a prescribed field of this instruction is decoded by microinstruction decoder 13 to output various control signals. The address of the next instruction from microprogram conter 14, the branch destination address held in register 12, the residual address of register 16, and so on are input to input parts AWD of multiplexer 17, and data corresponding to address data of input parts AWD is transmitted to memory part 11 by select command signal SLT from decoder 13 by multiplexer 17. Then, the waiting time of the operation processing unit is utilized to diagnose the data processing unit intermittently, thus executing diagnosis in on-line.
