Abstract:
A data processing system has an interrupt controller which provides an interrupt request along with a corresponding interrupt identifier and a corresponding interrupt vector to a processor. If the processor accepts the interrupt, the processor returns the same interrupt identifier value by way of interrupt identifier, along with interrupt acknowledge, to the interrupt controller. An interrupt taken/not taken indicator may also be provided. The communications interface used to coordinate interrupt processing between the interrupt controller and the processor may be asynchronous.
