Apparatus and method for interrupt control

摘要

The interrupt control apparatus in the present invention includes an interrupt vector register for holding address information corresponding respectively to interrupt resources of first type which are managed by an operating system and interrupt resources of second type which are not managed by the operating system, from among the interrupt resources. With regard to an interrupt generated by an interrupt resource of first type managed by the operating system, the interrupt control apparatus in the present invention launches a common interrupt entry function which is subject to a scheduling process common to the interrupt resources of first type, based on the address information of the interrupt vector register. At the same time, with regard to an interrupt generated by an interrupt resource of second type managed by a user, the interrupt control apparatus in the present invention launches an extended interrupt entry function which is not subject to the aforementioned scheduling process, based on the address information held in the interrupt vector register.
