An interrupt subsystem within a data processing system is scalable from low-end uni-processor systems to high-end multi-processor (MP) systems. This interrupt subsystem provides for queueing of interrupts from many sources, and for queueing of interrupts to the best processor in a multi-processor...http://www.google.es/patents/US5701495?utm_source=gb-gplus-sharePatente US5701495 - Scalable system interrupt structure for a multi-processing system
