Abstract
A multiprocessing system comprising a plurality of processors and a plurality of I/O devices. A central interrupt control unit functionally intercouples the plurality of processors and I/O devices. The central interrupt control unit is configured to receive interrupt signals from the I/O devices and is configured to distribute interrupt signals to the processors. One of the processors is configured as a master test processor to control a test mode for testing the central interrupt control unit. The master test processor is further configured to release the other processors and emulate a multiprocessing environment.
