Abstract

An interrupting node for providing interrupt requests to a pended bus. The 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. 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 interrupting node detects whether an interrupt acknowledge message on the bus includes destination data specifying that interrupting node, and provides an interrupt vector message to the bus in response.
