| AMD-8131 HyperTransport PCI-X Rev. 1.0 Tunnel This high-speed device provides two independent, high-performance PCI-X bus bridges, integrated with a high-speed HyperTransport technology tunnel. The tunnel function provides connection capability to other downstream HyperTransport technology devices, allowing greater system flexibility. As shown in Figure, the front-end HyperTransport interface (Side A) provides a configurable 16-bit wide communication path to the host, offering up to 6.4GB/s of bandwidth. Similarly, the back-end HyperTransport interface (Side B) provides a configurable 8-bit wide communication path to a downstream device, offering up to 3.2GB/s of bandwidth.
