2.1.1 Design Features
2.1.1.1 Intel740™ Graphics Accelerator
The Intel740™ graphics accelerator is the main component of the graphics reference design. This
component delivers high performance 3D/2D graphics and video capabilities. Each of the
interfaces are described below.
•
Accelerated Graphics Port (AGP) Interface. The AGP interface is a new interface designed
for 3D graphics. This interface provides increased bandwidth over PCI, side band addressing,
and AGP memory 3D texture storage. For a more complete description of the AGP interface
refer to the Intel740™ Graphics Accelerator Datasheet and AGP Specification.
•
Local Memory Interface. The memory interface on the Intel740™ graphics accelerator can
operate at speeds up to 100 MHz. An SDRAM interface supports SGRAM and SDRAM to be
used for different memory densities.
•
VMI Interface. A bi-directional VMI like port is incorporated into the Intel740™ graphics
accelerator providing a mechanism for affordable DVD. Video capture is also supported using
the video port pins.
•
TV Out Interface. Intel has worked with Rockwell* (Brooktree*) to design an interface
capable of supporting a high quality TV out chip. This interface allows the Intel740™ graphics
accelerator to output on a monitor, TV, or both.
•
BIOS Interface. The Intel740™ graphics accelerator supports a FLASH or ROM BIOS. Up
to 256Kx8 can be supported.
•
GPIO Interface. Nine GPIO signals exist on the Intel740™ graphics accelerator. GPIO[8:0]
allow for power management, DDC, I
2
C, thermal fault sensing, and other general features.
•
DAC Interface. An integrated DAC provides display resolutions up to 1600x1200.
