Abstract
PURPOSE: To make small the control memory and to make easy the control program change, by reading out and control the control program specific to the peripheral unit from the main memory, in the designation of the central processing unit for one peripheral unit.
CONSTITUTION: When the I/O control instruction is inputted to the I/O controller 104 from CPU101 via the I/O bus, the direct memory access controller DMAC103 is started based on the unit designation address. In this case, the control program specific to the I/O unit 105i corresponding to the address of designated unit is read out from the main memory 102 and it is stored in the control memory CS of the I/O controller 104. The I/O unit 105i designated is controlled with the program stored in this memory CS. Accordingly, a plurality of peripheral units can be controlled with one input and output control section to simplify the system constitution.
