HyperTransport Technology: Simplifying System Design

The HyperTransport technology I/O link is a narrow, high speed, low power I/O bus that has been designed to meet the requirements of the embedded markets, the desktop, workstation, and server markets, and networking and communications markets. HyperTransport technology links are capable of extremely fast signaling with clock speeds of up to 800 MHz, and Double Data Rate (DDR) memory signaling, to provide an effective throughput of 1.6 gigatransfers per pin-pair on a 32-bit link. The result is a maximum aggregate throughput of 12.8 gigabytes per second, per link. This paper focuses on the benefits that HyperTransport technology gives system designers and the advanced capabilities that HyperTransport technology offers.
