PURPOSE:To prevent a processing speed from being reduced by storing the address of an error at the time of detecting the error in a microinstruction, storing a correcting microinstruction also, and in a waiting state, correcting said address instruction by the stored correcting instruction. CONSTITUTION:At the time of detection an error in a microinstruction outputted from a control storage 80, the error is corrected when the error is correctable and the corrected microinstruction is stored in a corrected microinstruction storing means 25 without rewriting it in the control storage 80. Simultaneously, the address of the error is stored in an error address storing means 24. When a processor 10 aborts its processing and a wait signal 41 is outputted, an address selecting means 26 selects the address of the microinstruction having the error and stored in the storage 80 from the means 24 to return the corrected microinstruction from the means 25 to the selected address. |
