  • Apparatus and method for end of interrupt handling
    Patent number: 6754754
    Abstract: An interrupt vector is issued by an interrupt controller in response to an interrupt request. A processor executes an interrupt service routine in response to receiving the interrupt vector. Upon the completion of the interrupt service routine, the processor issues an end of interrupt vector to the interrupt controller. The interrupt controller substantially simultaneously compares the end of interrupt vector with a plurality of stored interrupt vectors.
