1.5. INTRODUCE THE PCI - BUS
Connecting devices to a CPU local bus can dramatically increase the speed of I/O-
bound peripherals with only a slight increase in cost over traditional systems.
This price / Performance point has created a vast market potential for local bus
products.
The main barrier to this market has been the lack of an accepted standard for local
bus peripherals.
Many mainboard and chipset manufactures developed their own local bus
implementations, but they are incompatible with each other.
The VL (Video Electronics Standards Association) local bus and PCI (Peripheral
Component Interconnect) bus specification was created to end this confusion.
The PCI - bus standard, under development since Jun. 1992, which is designed to
bring workstation-level performance to standard PC platform. The PCI - bus
removes many of the bottlenecks that have hampered PC for several years.
On the PCI - bus, peripherals operate at the native speed of the computer system,
thus enabling data transfer between peripherals and the system at maximum speed.
This performance is critical for bandwidth-constrained devices such as video,
multimedia, mass storage, and networking adapters.
PCI - bus standard provides end-users with a low-cost, extendible and portable local
bus design, which will allow system and peripherals from different manufactures to
work together.
1.6. FEATURES
q32 bits bus transfer mode.
qBus Master or Slave access.
qMemory burst transfer to 132 MB/sec.
q33 MHz operation speed.
q10 device loading ability.
qCPU independent.

1.7. 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.
