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.
