Multiprocessor system

Abstract

An interrupt notification network is provided for a multiprocessor system in which many processor units are installed. An interrupt notification source processor unit transmits an interrupt notification packet to an interrupt notification destination processor unit. The interrupt notification packet to be transmitted by the interrupt notification source processor unit contains an interrupt destination process ID. A control section for the interrupt notification network analyzes the transmitted interrupt notification packet, references a table that defines the correspondence between internally retained IDs of processes and processor units that perform the processes, determines the interrupt notification destination processor unit, and transmits the interrupt notification packet to the processor unit. Consequently, the multiprocessor system in which many processor units are installed is capable of performing an inter-processor unit multiplex coordination process for inter-processor unit process synchronization and process control, increasing the system throughput, and providing increased real-time capability.
