Microinstruction controlled arithmetic control unit
摘要:
A microinstruction-controlled arithmetic control unit including an inhibiting circuit enables prohibition, when parallel operation is not possible in the same cycle, of the execution of the succeeding microinstruction by the inhibiting circuit without the insertion of dummy microinstructions, and permits parallel operation, when parallel operation is possible in the same cycle, by releasing the function of the inhibiting circuit, thereby improving the operation speed.
