HyperTransport Technology Introduction

The CPU is the heart of the server. Recently, server vendors have adopted more and more technologies on the CPU to increase the performance of the server. Now even the redundancy technology is applied to the CPU, and now the general server is equipped with more than two CPU sockets, some have four or more. Here is an introduction to AMD chip technology: HyperTransport technology.

HyperTransport technology is an innovative technology that provides integrated circuit upgrades, near-speed, high-performance, and point-to-point connectivity. It features high-speed serial connectivity with 4, 8, 16 and 32-bit bandwidth and provides 12.8 GB per second bandwidth to support multiple GHz+ 64-bit processors and emerging I/O technologies such as Intel's InfiniBand And 10 Gigabit Ethernet. HyperTransport is a protocol, not just an entity interface, that can be upgraded to accommodate new applications. In the HyperTransport protocol, data is sliced ​​into data blocks or packets. Each data block can reach up to 64 bits.

HyperTransport technology helps reduce the number of rows in the system and provides a highly efficient link to embedded applications. With HyperTransport technology, chips in PCs (communicating networks and communication devices) can increase speeds by up to 40 times faster than current technologies. HyperTransport is specifically designed for chip sizes less than 0.13 microns.

The purpose of HyperTransport is not to replace other I/O technologies, but to provide a high-standard chip-to-chip internal connection that meets the data transfer requirements of memory and I/O components. It connects low-speed traditional I/O devices with high-speed new media I/O channels.

At present, AMD, Apple, Broadcom, Cisco Systems, nVIDIA, SGI, Sun Microsystem and Transmeta have formed a group to jointly develop HyperTransport technology. HyperTransport technology has gained strong industry support due to its compatibility with PCI systems. HyperTransport technology allows manufacturers of network devices to expand the number and bandwidth of their devices at once, or even without changing the software or architecture. The century of HyperTransport has come.
