Abstract
PURPOSE: To increase the processing capacity and others of the system by giving the comparison between the discriminating information memorized in the input/output unit and that of the processor which issues the request in case the input/output unit is being reserved and then accepting the request only when the coincidence is obtained through the above comparison.
CONSTITUTION: Input/output control units 6 and 7 are provided among processors 1 and 2 plus input/output units 11W13, and at least processor 1 or 2 is connected to unit 11W13 via unit 6 or 7. At the same time, units 6 and 7 possess discriminating two pieces of information 14 and 15 proper to units 11W13 to be connected to units 6 and 7 plus comparators 22 and 23 each. And the input/output request given to a certain input/output unit from a certain processor is accepted if the input/output unit is not being reserved. While in case the input/output unit is being reserved, the comparison is given between the discriminating information memorized in the input/ output unit and that of the processor which delivers the request. And the request is accepted only when the coincidence is obtained through the above comparison. As a result, the processing capacity and others can be increased for the system.
