In one embodiment of the invention, an apparatus includes address and data ports to receive an interrupt request signal in the form of address signals and data signals. The apparatus also includes decode logic to receive at least some of the address signals and data signals and provide a decoded signal at one of several decode output lines of the decode logic. A redirection table includes a send pending bit that is set responsive to the decode signal. In another embodiment, an apparatus includes dedicated interrupt ports to receive an interrupt request signal. The apparatus also includes address and data ports capable of receiving an interrupt request signal in the form of address signals and data signals, and decode logic to provide a decode signal at one of several decode output lines in response to reception of the interrupt request signal in the form of address signals and data signals. A redirection table includes a send pending bit to be set in response to either the interrupt request signal at the dedicated interrupt ports or in response to the decode signal.
