Abstract
PURPOSE: To increase the process speed greatly for the data processor by storing in advance the micro-routine required in future into the high-speed memory unit.
CONSTITUTION: The low-speed memory unit storing the plural micro-routines is provided, along with the high-speed memory unit to store the micro-routine read out from the low-speed memory unit. The mechanical orders are read out in sequence and in advance from the mechanical word program of main memory 1, and whether the micro-routine corresponding to the read-out mechanical order is transferred to high-speed buffer memory unit 26 or 33 is checked. And in case the micro- routine is not transferred yet, the routine is transferred and made to wait; while the routine is already transferred, it is made to wait as it is. And the waiting micro- routines are executed in sequence unless no branch exists on the mechanical word program. However, if the branch or the like exists, the reading is started newly with the mechanical order for the branching address.
