AMD-8132

HyperTransport PCI-X Tunnel

The AMD-8132 HyperTransport PCI-X 2.0 tunnel is a high-speed device that provides two independent, high-

performance PCI-X bus bridges, integrated with a high-speed HyperTransport technology tunnel. Designed for

operation in modes 1 and 2, the AMD-8132 component brings high-performance PCI-X 2.0 connectivity to AMD

Opteron processor-based systems with increased throughput, improved RAS capabilities, robust data

management, and enhanced HyperTransport technology connectivity. As shown in Figure 3-2, the front-end

HyperTransport interface (Side A) provides a configurable 16-bit wide communication path to the host, offering

up to 8 GB/sec. of aggregate bandwidth. Similarly, the back-end HyperTransport interface (Side B) provides a

configurable 16-bit wide communication path to a downstream device, offering up to 8 GB/sec. of aggregate

bandwidth.

The AMD-8132 HyperTransport PCI-X Tunnel provides high-speed PCI-X capability and offers the following

features:

• 16-bit HyperTransport interfaces (Side A and B) offering a maximum aggregate bandwidth up to 8 GB/sec.

on each side

• Two PCI-X bridges (A and B), each of which supports a 64-bit data bus

• Each bridge also supports Mode 1 PCI-X, conventional PCI protocol, and Mode 2 operation

• Each bridge supports independent transfer rates and operational modes:

• In PCI-X Mode 1, bridges support transfer rates of 133, 100, 66, and 50 MHz

• In PCI mode, bridges support transfer rates of 66, 50, 33, and 25 MHz

• 37.5 x 37.5 mm, 829-pin BGA package

• 3.3 volt PCI-X signaling; 1.2 volt link signaling; 1.8 volt core
