Coherent HyperTransport

Overview of AMD's CPU interconnect system. HT is awesome with just Opterons. The bandwidth is huge, and no need for a chip to negotiate on the bus with the coherent stuff. Apparently they also plan to license the technology so people can build specialized coprocessors. They'd plug in just like another CPU, and communicate with the other processors at FSB speeds. They give Java/XML as an example, imagine crypto offload or something too.
