Abstract
PURPOSE: To write microinstruction to one control memory block while reading and executing microinstructions from the other memory block, by providing at least two readable and writable control memory blocks.
CONSTITUTION: By using an address from microinstruction address register 13, microinstructions are read out from 1st control memory block 11 and inputted to microinstruction register 22, thereby controlling the data processor by those microinstructions. Next, the address of 2nd control memory block 12 is assigned by write address register 25 and a microinstruction of main memory unit 23 to be transferred is also assigned by main memory address register 24. Then, a write microinstruction from main memory unit 23 is sent to block 12 and written to a position assigned by the address.
