AMD-8131BLC Overview
24637 Rev 3.02 - August 10, 2004 AMD-8131TM PCI-X Tunnel Data Sheet AMD-8131TM HyperTransportTM PCI-X Tunnel Data Sheet 1 Overview Cover page The AMD-8131TM HyperTransportTM PCI-XTunnel (referred to as the IC in this document) is a HyperTransport™ technology (referred to as link in this document) tunnel developed by AMD that provides two PCI-X bridges.
AMD-8131BLC Key Features
- Side A is 16 bits (input and output); side B is 8 bits
- Either side may connect to the host or to a downstream HyperTransport technology pliant device
- Each side supports HyperTransport technology-defined reduced bit widths: 8-bit, 4-bit, and 2-bit
- Each side supports transfer rates of 1600, 1200, 800, and 400 mega-transfers per second
- Maximum bandwidth is 6.4 gigabytes per second across side A (half upstream and half downstream) and 3.2 gigabytes per se
- Independent transfer rate and bit width selection for each side
- Link disconnect protocol supported
- Two PCI-X (rev. 1.0) bridges: bridge A and bridge B
- Each bridge supports a 64-bit data bus
- Each bridge supports operational modes of PCI-X and legacy PCI revision 2.2 protocol
