System and method for coupling a local bus to a peripheral component interconnect (PCI) bus

摘要

A system and method for coupling a local bus to a PCI bus are provided. The system comprises a local bus interface for receiving signals from a microprocessor through a local address/data bus and a local control bus. The system further comprises a bus translator coupled to the local bus interface. The bus translator determines if the microprocessor will access a target peripheral PCI device coupled to the local address/data bus. A PCI control bus interface is coupled to the bus translator and signals the target PCI peripheral device via a PCI control bus, such that the local address/data bus and the PCI control bus define a PCI bus.
