ABSTRACT:
Apparatus and method for servicing interrupt requests on a pended bus. An interrupt servicing node provides interrupt acknowledge messages including destination data specifying a particular interrupting node at times when the interrupt servicing node is ready to service an interrupt request message. The interrupt servicing node includes storage for specifying the identity of a particular interrupting node and for indicating that an interrupt request is pending from a particular interrupting node. An interrupting node provides to the pended bus an interrupt request message including ID data for identifying the interrupting node as the source of an interrupt request. The interrupting node detects whether an interrupt acknowledge message on the bus includes destination data specifying that interrupting node.
