ABSTRACT:
A multiprocessor system and method wherein one of the processors is assigned the responsibility of handling interrupts and identifying the next processor to handle an interrupt. When that processor switches tasks and determines that it is no longer the least important processor as far as task priority is concerned, it will then select and transfer its interrupt-related responsibilities (i.e., handling the interrupt and determining the next interrupt-handing processor) to the processor which is executing the least important task. The selected processor will then be designated for handling interrupts unless and until it undergoes a task switch and selects a different processor.
