Abstract
PURPOSE: To increase the reliability and processing speed, by improving the lowering in the number of processing steps in a given time, through the classification of microprogram instructions into those in which the delay in the execution time is a problem and those not a problem.
CONSTITUTION: The unit consists of the microprogram memory 101, address register 102, circuit 104 correcting the readout of the memory 101 according to the output of the circuit 103, microprogram instruction register 105,FF 106, error processing circuit 107, interpreting means 108, FF109, inhibit gate 151, AND gates 152 to 154. When FF109 is "1", if readout error is detected 103 at the readout of the microprogram instruction, suitable processing is made even if an output is given to the circuit 107 via the gate 153. Otherwise, if readout error, processing is executed while correcting it with the correction circuit 104.
