It is an established high-speed bus standard that reduces data bottlenecks and boosts the performance of current and future PCs and communications equipment, including PCs, workstations, servers, Internet routers, optical switches, enterprise networks, central office equipment, and cellular base stations, to name a few. The HyperTransport Fabric HyperTransport is an emerging interconnect standard that was co-developed by AMD and API NetWorks. Initially, HyperTransport was developed to replace the PCI bus on Workstations and PC platforms. Today, HyperTransport is available on a wide range of MIPS, x86, and, in the future, general-purpose DSP processors. The host initializes a chain making a host and one single ended slave as the smallest possible construct and a host with 31 tunnels devices the largest.
All transactions originate and terminate via a host port.
The tunnel and single ended slave are considered peripherals or slaves. A switch passes data to and from one HyperTransport chain to another. Data Management One of the more complex data management tasks in a system is tracking a resource and mapping the available resource so the host can effectively utilize it. When the host writes to that address range, the HyperTransport logic transfers and then writes that data into the target device's memory without host processor intervention. Commands are four bytes long and begin with a six-bit command type field.
