Books in the series are intended for use by hardware and software designers, programmers, and support personnel. The primary use for HyperTransport is to replace the Intel-defined front-side buswhich is different for every type of Intel processor.

FireWire System Architecture 2nd Edition. Universal Serial Bus System Architecture. From Wikipedia, the free encyclopedia.

MindShare – HyperTransport Interconnect Technology

Get the MindShare Library. HyperTransport is packet -based, where each packet consists of a set of bit words, regardless of the physical width of the link. The Unabridged Pentium 4.

AMD started an initiative named Torrenza on September 21, to intercknnect promote the usage of HyperTransport for plug-in cards and coprocessors. HyperTransport TM technology has revolutionized microprocessor core interconnect.

Add to that In contrast, HyperTransport is an open specification, published by a multi-company consortium. The “DUT” test connector [5] is defined to enable standardized functional test system interconnection.

Transfers are always padded to a multiple of 32 bits, regardless of their actual length. Some chipsets though do not even utilize the bit width used by the processors.


For instance, a Pentium cannot be plugged into a PCI Express bus directly, but must first go through an adapter to expand the system. Retrieved 24 May Retrieved from ” https: Hypertranspprt number of bit times required depends on the link width. Reads also require a response, containing the read data. Topics include system architectures, parallel bus technologies, serial bus technologies, and processor architectures. Dawn of the Mongol Empire. A connector specification that allows a slot-based peripheral to have direct connection to a microprocessor using a HyperTransport interface was released by the HyperTransport Consortium.

HyperTransport supports an autonegotiated bit width, ranging from 2 interxonnect 32 bits per link; there are two unidirectional links per HyperTransport bus. Jay Trodden is an electrical engineer with over 15 years experience in electronics hardware design. While HyperTransport itself is capable of bit width links, that width is not currently utilized by any AMD processors. There has been some marketing confusion between the use of HT referring to H yper T ransport and the later use of HT to refer to Intel ‘s Hyper-Threading feature on some Pentium 4 -based and the newer Nehalem and Westmere-based Intel Core microprocessors.

This book is a must-have for anyone in the semiconductor and system industries who is technolovy working with or exploring the potential of working with HyperTransport technology. Retrieved 17 January The first word in a packet always contains a techmology field. There are two kinds of write commands supported: HyperTransport packets enter the interconnect in segments known as bit times. Wikipedia articles needing clarification from June All articles with dead external links Articles with dead external links from April Articles with permanently dead external links.

A single HyperTransport adapter chip will work with a wide spectrum of HyperTransport enabled microprocessors. Companies such as XtremeData, Inc. Links of various widths can be mixed together in a single system configuration as in one bit link to another CPU and one 8-bit link to a peripheral device, which allows for a wider interconnect between CPUsand a lower bandwidth interconnect to peripherals as appropriate.


He has authored 14 books covering various aspects intercobnect computer hardware and system design.

These are typically included in the respective controller functions, namely the northbridge and southbridge. HyperTransport can also be used as a bus in routers and switches. It is a high-speed, hyperransport latency, point-to-point, packetized link.


Views Read Edit View history. This page was last edited on 11 Julyat The current specification HTX3. Archived from the original on Non-posted writes require a response from the receiver in the form of a “target done” response. By using this site, you agree to the Terms of Use and Privacy Policy. With extensive new content authored by Brian Holden, the long-time technical chair of the HyperTransport Consortium, the book is a personal trainer that effortlessly walks the reader through HyperTransport’s strong set of features and rich potential.

The issue of latency and bandwidth between CPUs and co-processors has usually been the major stumbling block to their practical implementation. It also supports link splitting, where a single bit link can be divided into two 8-bit links.

This means that changes in processor sleep states C states can signal changes in device states D statese.
