Abstract

A system and method for triggering interrupt service routines is disclosed. The system can be implemented in a computer readable medium that includes logic for receiving first and second signals. The first signal triggers a first interrupt that triggers a first interrupt service routine that is designed to process a first task. The second signal trigger is designed to cause the processing of a second task. The medium also includes logic for determining if the second task is a high priority task, and logic for creating a second interrupt if the second task is a high priority task. The medium further includes logic for completing the first interrupt service routine before processing a second interrupt service routine. The second interrupt service routine is triggered by the second interrupt. The second interrupt service routine is designed to complete the high priority task. And, the medium includes logic for returning to a main loop after completing the second interrupt service routine.
