A technique for interrupt distribution in a multiprocessor system

Abstract

A technique for distributing interrupts in a multiprocessor system is described. The technique employs a decentralised control and arbitration technique which is very modular and inexpensive in interconnections. Interrupt vectoring is supported and individual processor latency to interrupts are masked from the distribution system so that high-speed distribution can be achieved. The use of the technique obviates the need to have dedicated interrupt connections
