HyperTransportв„ў System Architecture

At the time of this writing, the HyperTransport I/O Link Specification Revision 1.04 is released. The 1.04 revision of the specification does not deal with the networking extensions but much of the work on the HyperTransport 1.05 and 1.1 revisions has been done by the HyperTransport Technical Working Group, and quite a bit of preliminary information on this important addition to the protocol has been released.

The networking extensions are backward compatible with the 1.04 and earlier revisions. Compatibility extends to any mix of devices which may or may not support the extensions.

This chapter presents material based on information currently available. Check http://www.hypertransport.org for updated information on all revisions to the specification.
