HyperTransport

A high-speed interconnection architecture between integrated circuits, introduced in 2001. Code-named Lightning Data Transport and developed by AMD and others, the HyperTransport I/O Link Specification defines a protocol and electrical interface between the CPU, memory and peripheral devices.

Since its introduction, HyperTransport's maximum aggregate bandwidth of 32-bit links progressed from 12.8 to 41.6 Gbytes/sec. Version 3.0 also added dynamic link splitting under software control. Called "Un-Ganging," it enables a single unidirectional link to be split into two; each at half the original bit width. HyperTransport (HT) was designed to be fully compatible with legacy PCI (running at 33 or 66 MHz) plus PCI Express and PCI-X technologies.
