What is Hypertransport?
Hypertransport is a technology designed to replace traditional input/output bus technology on computers. This technology is much faster than previous technologies. It is compatible with most microprocessors, regardless of which company has produced them.
Input/output bus or I/O bus is a data path that connects computer processors to each other or with coprocessors or other components. Until Hypertransport was invented, the industry (PCI) was connected to the connection of various hardware devices. This technology is still used on many computers and can connect network cards or modems to the computer.
When computer technology has evolved, traditional I/O buses could not keep up with the development of processor speeds. In 1997, Hypertransport Technology Advanced Micro Devices (AMD) developed to solve this problem. Seven other technologists joined AMD in 2001 with AMDof the societies to create a consortium of hypertransport. The consortium is a non -profit group of the Thv area of the management and licenses of transport technology within the computing industry. His membership consists of various companies and academic organizations.
Hypertransport has many advantages over older bus technologies. This requires less electricity, so users do not have to worry about your computer cooling. It is also narrow, allowing greater flexibility. In the past, bus manufacturers would only expand the size of the bus to increase speed. At some point, it became impractical. Newer technology is able to move more data in a smaller space so that the bus can remain narrow.
The bus contains reserved pins that send only specific types of information. This means that the pins are not used if the type of data is not a type that generally manipulates. With technologyHypertransports are able to transport all types of data, so all pins can be used every time data is sent. Data is sent in 32 -bit packets that use the maximum collection width to send the largest amount of information physically.
Every hypertransport has two data lines. Each line can move 1.6 billion data per second for each pair of pins. Because it can send more data of fewer pegs, production costs will be reduced.
technology also creates reserved lines for each device. With traditional bus technology, all equipment share one bus. This can slow down the processing if more than one device approaches the bus at a time. Hypertransport creates a line for each device and solve this problem.
