Abstract
An apparatus for controlling interrupts is provided in a system controller SC of a multiprocessor system in which a plurality of instruction processors IP share a main storage MS and a channel controller CHC through the system controller SC. The apparatus for controlling interrupts holds I/O interrupt control data for each of the instruction processors IP, and selects the most suitable instruction processor IP to process an I/O interrupt, without receiving responses from all of the instruction processors IP.
