Abstract
A method and structure(s) for providing a data path between and among nodes and processing elements within an interconnection fabric are described. More specifically, a device comprising a first circuit configured to couple between a first bus and a link is described. The circuit may be configured to operate as a bridge, support PCI configuration cycles, send outgoing information serially through the link in a format different from that of the first bus, and allow a host processor, communicating through the first bus, to selectively address one or more remote devices to which the device is configured to allow access. In some embodiments, the first circuit may support “spoof-proof” data protocols, and the device may operate in multiple modes including root bridge, leaf bridge, and gateway mode. Multiple addressing models may also be used.
