INTERRUPT METHOD IN MULTI-PROCESSING SYSTEM

摘要

The method is to handle the interrupt request from more than two interrupt requester. The method comprises steps: (A) receiving interrupt request transmitted from multiple CPUs; (B) generating selection signal by a interrupt request controller (1) according to the priorities of the CPUs; (C) forming a signal transmitting path between the selected CPU and system bus according to the selection signal; (D) receiving interrupt request from an interrupt handler adopter of different processor board; (E) generating a path selection signal related tothe interrupt request; and (F) setting the signal transmitting path between a system bus and a processor deposited at a processor board having the interrupt handler adopter (a).
