Abstract
A multi-processor computer system includes at least a first and second processor coupled to a host bus. The first processor accesses a first set of registers using a first plurality of addresses over the host bus. A second processor accesses a second set of registers using the first plurality of addresses over the host bus. A first integrated circuit forms a bridge between the host bus and an input/output bus. The first integrated circuit receives access requests for the first and second sets of registers from the first and second processors, respectively. A second integrated circuit, coupled to the input/output bus, includes a first and a second local interrupt controller, the first and second sets of registers being part of the first and second local interrupt controllers. The first integrated circuit, responsive to an access request from one of the processors to one of the first plurality of addresses, outputs information on the input/output bus indicating the address of the register being accessed and which of the first and second processors made the access request, thereby specifying one of the first and second sets of registers.
