AMD AMD-8131BLC
The AMD-8131TM HyperTransportTM PCI-X Tunnel (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.FEATURES
HyperTransport technology tunnel with side A and side B.● 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 compliant 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 second across side B.
● 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.
● Bridges support 133, 100, and 66 MHz transfer rates in PCI-X mode.
● Bridges support 66 and 33 MHz transfer rates in PCI mode.
● Independent transfer rates and operational modes for each bridge.
