What is Hyper Transport Technology?

Have you heard about Hyper Transport Technology? Hyper Transport technology may be a high-speed, low-latency, point-to-point link designed to extend the communication speed between integrated circuits in servers, computers, networking, and embedded systems and telecommunications equipment up to 48 times quicker than some existing technologies.

Hyper Transport technology

This is typically integrated directly into the processor, but in some cases Hyper Transport is employed as an integrated, high performance I/O bus that pipes Firewire, USB, PCI, PCI-X, and video/audio links through the system.<!–more–>

The demand for quicker processors, memory and I/O could be a familiar refrain in market applications starting from personal computers and servers to networking systems and from video games to office automation equipment. Moreover Once data is digitized, the speed at which it’s processed becomes the foremost determinate of product success.Quicker system speed results in quicker processing, also this processing results in quicker system performance. And performance leads to greater success in the marketplace.

This obvious logic has LED a generation of processor and memory designers to concentrate on one overriding objective – squeezing more speed from processors and memory devices. In Addition the Processor designers have responded with faster clock rates and super pipelined architectures that use level 1 and level 2 caches to feed quicker execution units even quicker.what is hyper transport technology

Faster Execution

Increased processor speeds, quicker memories, and wider I/O channels aren’t always practical answers to the requirement for speed. The main drawback is integration of more and quicker system components. Faster execution units, quicker memories and wider, quicker I/O buses result in crowding of more high-speed signal lines onto the physical printed circuit board. In Addition one aspect of the integration drawback is that the physical issues posed by speed

Faster signal speeds result in producing issues because of loss of signal integrity and greater susceptibility to noise. In fact very high-speed digital signals become high frequency radio waves exhibiting an equivalent problematic characteristic of high-frequency analog signals. Also this breaks havoc on printed circuit boards manufactured using normal, inexpensive materials and technologies.

Technologies like high-speed networking (InfiniBand, Gigabit Ethernet, etc.) and wireless communications (Bluetooth) are permitting more devices to exchange growing amounts of information at quickly increasing speeds. Software technologies are evolving; leading to breakthrough strategies of utilizing multiple system processors.

In addition this technology reduces the number of buses in a system; which may reduce system bottlenecks and modify today’s faster microprocessors to use system memory more with efficiency in high-end multiprocessor systems.

Hyper Transport Technology is meant to:
  • Provide considerably more bandwidth than current technologies
  • Low pin counts and low-latency responses are used
  • Maintain compatibility with legacy computer buses while being extensible to new SNA (Systems Network Architecture) buses
  • Appear transparent to operating systems and provide very little impact on peripheral driverswhat is hyper transport technology12
Now let us see some of the advantages of Hyper Transport Technology:
  • Packet based technology
  • Provides low latency
  • Has high bandwidth
  • Reduces number of buses
  • Decreases packet overhead

Now we can say that there will be tremendous change in Hyper Transport Technology. In fact Hyper Transport Technology can bring a revolution in the bus architecture.
