Abstract

PURPOSE: To increase the probability of absence of error in memories and to make higher the data processing efficiency, by refreshing the microprogram when the microprogram control unit is in idling state.
CONSTITUTION: A control memory 4 is provided with an error correction section 4', and the data stored to the program register 5 and memory register 7 from the memory 4 are written in the memories 5 and 7 after being corrected at the correction section 4' if one bit error is present in the data. Accordingly, when the microprogram control unit is in idling state and the content of the register 7 is restored in the same address stored up to now with the microprogram for control in the memory 4, even if one bit error is present in the storage data up to now, the error is corrected and refreshed resulting in increasing the data processing efficiency.
