Abstract
PURPOSE: To make it possible for processors to use input-output units simultaneously, by providing a memory unit in which processor numbers are made to correspond to input-output unit numbers.
CONSTITUTION: Memory unit 34, storing coordinates between input-output units and processors, has as an input circuit the IO address selecting circuit consisting of input-output unit number line gate 31 from processor 10, gate 32 of the input-output unit number line from input-output unit interface part 20, and OR gates 33 for them and is further equipped as output circuits gate groups 350W352 that select control lines operating respective processor interface parts 41W43 and interruption permission selecting circuits 360W363 that select interruption permitting signals from processor interface parts 41W43 and transfer them to input-output unit interface part 20.
