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 further speed the transaction.
