scope:

This is a full-use standard whose scope is to extend the already defined asynchronous and isochronous services of High Performance Serial Bus beyond the local bus by means of a device, the bridge, which consists of two nodes, each connected to a separate bus and both interconnected by implementation-dependent means.

The project is intended to standardize the model, definition, and behaviors of High Performance Serial Bus bridges, which are devices that may be used to interconnect two separately enumerable buses. This project extends IEEE Std 1394-1995, as amended by IEEE Std 1394a-2000, and IEEE Std 1394b-2002, and is based upon those documents as well as upon IEEE Std 1212-2001, Control and Status Registers (CSR) Architecture for microcomputer buses.

NOTE-The set of IEEE 1394 standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming implementations. These standards are functional descriptions. An implementation may employ any design whose behavior is compliant with the pertinent standards.
