  • Patent number: 5881294
    Abstract: A system for transforming computer system interrupts from state based interrupts to event based interrupts. The system of the present invention includes an interrupt acknowledge detection circuit adapted to detect an interrupt acknowledge from a computer system. The interrupt acknowledge detect circuit is coupled to a vector match circuit. The vector match circuit is adapted to receive an interrupt vector from the computer system and determine whether the interrupt vector matches a predetermined interrupt vector within the vector match circuit. The vector match circuit is, in turn, coupled to an interrupt assertion circuit. The interrupt assertion circuit includes an internal interrupt request line and an external interrupt request line. The interrupt assertion circuit functions by asserting an interrupt signal via the external interrupt request line to the computer system in response to receiving a state based interrupt via the internal interrupt request line.
