Abstract
An interrupt handling system and method for a multiple processor system permit the interrupts generated by one or more hardware devices to be routed and prioritized dynamically. In particular, the interrupt controller permits the interrupts to be dynamically routed between the multiple processors and permits a particular interrupt to be dynamically assigned a priority level. The interrupt handling system also permits software based interrupts wherein, for example, one processor may interrupt another processor.
