1.6 What is AGP

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-data rate is used, the port can transmit data

at 533MB/sec (66.6*2*4). The read-queue can be used to pipeline 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 speed up the transaction.
