PURPOSE:To suppress the degradation of processing performance at the time of the correction of a one-bit-error by executing write-in to a control storage part by using an error address data register with a microinstruction when an error correction microprogram is started. CONSTITUTION:When the one-bit-error of the control storage part 1 occurs in some microprogram processing, it is corrected immediately, and after execution, the processing is continued, and consequently, an address at the time of the occurrence of the error and data after the correction are held in an error address data register 11. Then, when the error correction microprogram is stared, the write-in to the control storage part 1 is executed by using the error address data register 11 with the microinstruction. Thus, the degradation of the processing performance accompanied with the correction of the one-bit-error can be suppressed to the minimum. |
