What Does HyperTransport Bus (HT) Mean?
A HyperTransport (HT) bus is a bus technology developed by AMD Inc. and used in microprocessors as a low-latency, high-speed, point-to-point link specifically designed to increase the communication speed between the components in a computer system, servers, embedded systems, and networking and telecommunications equipment at up to 48 times compared to older or existing transport technology.
HyperTransport is packet-based, and it sends data in a packet that consists of 32-bit words. It also has power management and is compliant with advanced configuration and power interface specifications. It was designed to:
- Use low pin counts and low-latency responses
- Be transparent to the operating systems and make very little impact on peripheral drivers
- Maintain compatibility with legacy PC buses while being extensible to new systems network architecture buses
- Provide significantly more bandwidth than technologies at the time of its release
HyperTransport is handled by the HyperTransport Consortium, which includes AMD Inc., Apple Inc., NVIDIA Corp. and CISCO Inc. among many others.
A HyperTransport bus may also be known as a lightning data transport (LDT) bus.
