Abstract
The transmission of interrupts is described where the interrupt is represented at a peripheral device by the electrical level of a conductor but where it is conveyed to a receiving module by way of a message packet routed along a routing path. According to one aspect, the message packet includes the identification of the peripheral device which generated the interrupt and the receiving module acts on the message packet to implement an interrupt handling routine depending on the identification of the peripheral device. According to another aspect, the message packet includes a transaction identifier which uniquely identifies one of a series of interrupts, and the receiving module generates a response packet containing that transaction identifier thereby allowing the peripheral device to monitor whether or not its interrupts have been treated properly.
