Abstract

PURPOSE: To realize the enhanced reliability as well as the increased process velocity by displaying the error according to the contents of microprogram order register or discontinuing the microprogram operation in case some reading error is detected through the error detecting circuit.
CONSTITUTION: Microprogram memory 101 stores the microprogram order group; the reading error given from memory 101 is detected through error detecting circuit 103; and the reading contents from memory 101 is corrected (104) according to the output of circuit 103. Now, in case some reading error is detected through circit 103, the error is displayed in accordance with the contents of microprogram order register 105, or the operation of the microprogram is discontinued (151). As a result, the high reliability and the process velocity can be realized.
