APPENDIX A
What is the AGP (Accelerated Graphics Port) ?
The Accelerated Graphics Port (AGP) is a new port on the
Host–To–PCI bridge device that supports an AGP port. The main
purpose of the AGP port is to provide fast access to system memory.
The AGP port can be used either as fast PCI port (32-bits at
66MHz VS. 32-bits at 33MHz) or as an AGP port which supports 2x
data rate, a read queue, and side band addressing. When the 2x date is
used the port can transmit data at 533MB/sec. (66.6
2
4). The
read-queue can be used to pipline reads removing the effects of the
reads latency. Side band addressing can be used to transmit the data
address on a separate line in order to further speed the transaction.
