Abstract: PURPOSE:To eliminate the conflict of a main memory by extending the machine cycle time of a microinstruction if said instruction which performs new start of the main memory during operation of the main memory is outputted. CONSTITUTION:An FF15 and an FF16 store only the reading start and the writing start respectively.

The input 7 is set at logic 0 by the gate 21 when the output 17 is set at logic 1, i.e., in a reading start mode. Thus a synchronizing signal 6 is extended. While the output 18 is set at logic 1 in a writing start mode. At the same time, the input 7 is set at 0 to extend the signal 6 only in case a start request for main memory is delivered (i.e., the access start signal 19 is se at 1) after a microinstruction which started the writing. Then the processing is advanced for the microinstruction.
