ABSTRACT:
This invention relates to an arrangement for distributing interrupts within a multiprocessing system and for processing personal computer (PC) interrupts as well as multiprocessor interrupts in that system. New interrupts are diverted from processors that have recently processed an interrupt, thus preventing any one processor from being overloaded with an interrupt processing work load. Some of the processors are equipped to process PC interrupts and multiprocessing system interrupts. In each processor classes of interrupts may be masked out. A distributed arbitrator is used to allocate an interrupt among a plurality of processors available to process the interrupt.
