摘要
A method and apparatus to bridge between the PCI bus and a RISC processor interface bus. In one embodiment, the present invention is a single-ASIC implementation rather than a design using multiple discrete circuit components. The invention incorporates a method and apparatus that will minimize subsystem latencies and inefficiencies in order to maximize data throughput and system performance. In yet another embodiment, the RISC processor interface bus is the AMBA ASB bus. The invention further provides an Advanced RISC Machine interface bus unit which uses an improved clock crossing handshake mechanism that can support a range of clock frequencies on the AMBA ASB bus.
