What is HyperTransport Technology?

HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a bidirectional serial/parallel high-bandwidth, low-latency computer bus that was introduced on April 2, 2001 [1]. The HyperTransport Technology Consortium is in charge of promoting and developing HyperTransport technology. The technology is used by AMD and Transmeta in x86 processors, PMC-Sierra, Broadcom, and Raza Microelectronics in MIPS microprocessors, ATI Technologies, NVIDIA, VIA, SiS, AMD, and HP in PC chipsets, HP, Sun Microsystems, IBM, and IWill in servers, Cray, Newisys, and QLogic in high performance computing, and Cisco Systems in routers. Notably missing from this list is semiconductor giant Intel, which continues to use a shared bus architecture.he Integrated Drive Electronics Interface, or IDE Interface, is the most widely used interface for connecting storage devices such as Hard Drives, CD-ROMs, CDRWs, DVD-ROMs, and DVD+-RWs. Other common names for this interface include Parallel ATA, PATA, ATA, and UDMA. An extension of the IDE interface is the Enhanced IDE interface – EIDE Interface – which, when introduced, allowed for drives larger than 528MB.
