PDF Version
AMD introduces the AMD-8151™ HyperTransport™ AGP3.0 graphics tunnel enabling
stunning graphics performance onto platforms implementing HyperTransport
technology. The AMD-8151 is an AGP3.0-compliant graphics controller offering
performance modes up to AGP-8X. The tunnel function provides connection
capability to other downstream HyperTransport technology devices, allowing
greater system flexibility.
As shown in Figure 1, 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 1.6GB/s of bandwidth. |
