ABSTRACT:
A method and apparatus for extending a PCI bus interface to a remote I/O backplane through a high speed serial link, providing a large number of I/O slots to alleviate packaging requirements. The apparatus includes a local and a remote serial bridge coupled by a serial link, which is used to transceive messages. Each serial bridge may reside either on a PCI add-in card, or directly on a motherboard. The bridge uses data buffering and a handshaking request and acknowledge protocol to assure accurate and timely data transfer.
