System Board 4-13
Graphics Controller
The graphics controller is integrated on the Intel 82810 Graphics and Memory
Controller Hub. The hub is specifically designed for graphics-intensive
operations, including 3D and 2D effects, texture mapping, text and color pixel
amplification, and video acceleration. The controller minimizes bus traffic by
off-loading the tasks normally performed by the processor, providing 64-bit,
high resolution performance for demanding True Color displays and other
sophisticated graphics functions.
The Graphics and Memory Controller Hub supports motion video and motion
video playback hardware. Support includes:
!
MPEG-2 decode
!
Motion Video Acceleration.
MPEG is a compression/decompression standard developed by a professional
video group called the Motion Picture Experts Group. MPEG produces full-
screen, 30-frames-per-second (fps), broadcast-quality digital video.
Integrated Audio
Audio is integrated on the system board through the Intel I/O Controller Hub.
The hub supports the AC’97 Link for Audio and Telephone Codec (AD 1881).
The chip provides 16-bit stereo audio.
