Abstract

PURPOSE: To increase the processing efficiency of the overall system, by giving priority to the operation of unit and performing data transfer through the effective use of the time when the unit performs no operation for processing.
CONSTITUTION: The data giving and reception is made via the buffer memory 2 with the control of the disc controller 3, between CPU1 and the magnetic disc unit 4. In this case, the buffer memory controller 5 is provided, the data giving and reception is inhibited between CPU1 and the memory 2 when the data readout/ write-in of the magnetic disc 4 is made, and it is made at the time other than the above. Thus, the idle time of the disc unit 4 is effectively utilized for the data transfer.
