	Accelerated Graphics Port - Biocrawler (Site not responding. Last check: 2007-10-18)
		The Accelerated Graphics Port (also called Advanced Graphics Port) is a high-speed point-to-point channel for attaching a single device (generally a graphics card) to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.
		AGP originated from Intel, and it was first built into the 440LX chipset for the Pentium II microprocessor in 1997.
		AGP cards generally slightly exceed PCI cards in length and can be recognized by a typical "hook" at the inner end of the connector, which does not exist on PCI cards.

	AGP - Accelerated Graphics Port
		Located on the motherboard, an accelerated graphics port (AGP) is a dedicated high-speed port for moving large blocks of data between a PC graphics controller and the system memory.
		Accelerated Graphics Port or Advanced Graphics Port (depending of which manufacturer's point of view), a new bus, designed by Intel, to be used by graphics boards.
		The AGP main memory use is dynamic, meaning that when not being used for accelerated graphics, main memory is restored for use by the operating system or other applications.

	Intel unveils architecture for 3-D uses - Accelerated Graphics Port - Company Business and Marketing Electronic News - ...
		Intel's Accelerated Graphics Port (AGP) complements the company's Peripheral Component Interconnect (PCI) bus by offering a dedicated pipeline for 3-D functions such as rasterization, z-buffering, display buffering and alpha-blending from the graphics frame buffer.
		With a specification scheduled for late 2Q96, Intel's AGP will be similar to the PCI bus in terms of its data transmission technique and is slated for release as a 32-bit, 66MHz port, although the company expects the path will migrate to 64 bits and 133MHz as the graphics demands grow.
		Although the AGP allows main memory to share in the storage of graphics data, the new architecture does not signal an Intel trend toward total reliance on system DRAM.

	Intel v. Via
		The AGP Specification was developed entirely by Intel as an industry standard, without involvement from any SDO or other industry group.
		AGP was promoted by Intel as an "open specification" and was made available to the industry by a license that could be downloaded from Intel’s web site.
		Specifically, the Court relied upon the fact that the AGP 2.0 Specification "makes clear that even ‘optional’ features, such as Fast Write still have a ‘required’ implementation of exceeding exactitude." Intel witnesses agreed that "optional" features had to be implemented as required by the AGP 2.0 Specification.

		As computers became increasingly graphically oriented, successive generations of graphics adapters began to push the limits of the PCI bus, leading to the development of the AGP bus, dedicated to graphics adapters.
		AGP also uses sideband addressing, meaning that addressing for packets is carried outside of the packet, so the entire packet does not need to be read to get addressing information.

		Though AGP is geared towards the Pentium II and it's Dual Independent Bus (DIB) architecture, you don't need a Pentium II processor to take advantage of the new technology, since the use of AGP doesn't depend on the CPU type.
		AGP graphic chips have the capability to access main memory directly for the complex operation of texture mapping.
		Thus, of course AGP is going to win out over PCI since the large amount of data can be read directly from the system memory rather than having to be loaded into the graphics card's memory.
