Interrupt Management System and Interrupt Management Method using Expanded Interrupt Vectors

摘要

PURPOSE: A system and method for controlling an interrupt using an expanded interrupt vector is provided to process interrupts being generated from more interrupt sources than interrupt sources responding to an interrupt vector area provided from a micro processor. CONSTITUTION: An expansion interrupt vector recording unit(19) records address information of a plurality of interrupt processing routines and comprises a plurality of vectors storing address information of each interrupt processing routine. An interrupt polling unit(18) selects one interrupt out of non-processed interrupts and extracts and outputs address information of an interrupt processing routine corresponded to the selected interrupt from the expansion interrupt vector recording unit(19). A shadow register(17) stores output information of the interrupt polling unit(18). An address remapping unit(13) receives address information of the original interrupt vector being generated from a micro processor(11) and generates address information of the shadow register(17) instead of the address information of the original interrupt vector.
