Abstract
PURPOSE: To obtain a constitution in which the power source controller, that controls power source units provided at various units used by the information control system, is controlled by program, thereby making it possible to additionally install devices, only by altering the contents of the control memory unit.
CONSTITUTION: An interface circuit is provided which receives commands from the CPU through the I/O bus. This interface circuit is provided with command receiver 11, which receives commands from the I/O bus, and command controller 12 which receives as input the device address from the I/O bus through address receiver 10 and controls the power sources of devices by the output from command receiver 11. Further, the interface circuit is provided with power source control memory unit 15, which stores information concerning turning ON/OFF the power source unit, control memory address circuit 16, which specifies the memory unit 15 by means of the address of controller 12, and control computation unit 17 which decodes the information of memory unit 15 and executes control. By applying the output of this control computation unit 17, together with the output which has been obtained from the output of controller 12 through sequential and individual ON/OFF controllers 13 and 14, to output controller 18, power source units can be controlled by program.
