Abstract

PURPOSE: To perform the input and output operation without degrading of efficiency for operational processing, by making the input and output mechanism independent from the operational processing function and switching the connecting the data storage memory unit with the buses.
CONSTITUTION: When the central processing unit inputs data from the input and output unit 4, the memory unit 2 gives the switching command to the memory switching circuit block 8 to enable the access from the I/O bus 9 present at the input and output control unit. Next, the central processing unit 1 gives the start command to the input and output control unit 7 to start the data transfer. At the end of the data transfer, the central processing unit 1 gives the switching command to the memory switching circuit block 8 to enable the access of the memory unit 2.
