METHODS AND APPARATUS FOR DISTRIBUTING INTERRUPTS

The present invention relates to handling interrupts in a multiprocessor system. An interrupt controller can receive input from a variety of interrupt sources, such as peripheral components and peripheral interfaces. Interrupts and their associated characteristics are identified. In one example, interrupt characteristics can be compared with characteristics of other interrupts handled by processors in the multiprocessor system. Interrupt characteristics are used to select a processor to run a routine for handling the associated interrupt. Intelligent selection provides efficient and effective distribution of interrupts.
