4-1. VGA Feature
ENDAT-3400M provides integrated S3 Graphics UniChrome™ Pro IGP, featuring a
2D/3D AGP8X graphics core with integrated MPEG-2 decoding and MPEG-4
acceleration for smooth DVD and digital video playback, the VIA 'Luke' CoreFusion
processing platform also features support for high bandwidth DDR 333/400
memory, motion compensation and DuoView for the latest multiple format flat panel
display devices.
With an internal data flow equivalent to what is available to the latest AGP 8X
graphics cards, Unichrome Pro has separate 128-bit data path between the North
Bridge for pixel data flow and texture/command access. Separate 128-bit 2D and
3D graphics engines ensure optimal performance for all multimedia, entertainment,
and productivity applications.
Unichrome Pro includes native support for the most popular digital video and audio
playback through hardware MPEG-4/-2 acceleration and acclaimed VIA Vinyl Audio
suite, delivering spectacular playback for entertainment devices.
Unichrome Pro with its optimized shared memory architecture and high definition
video support through the Chromotion CE Video Display Engine offers a
breathtaking visual experience for the latest HDTV format displays.
The on-board Graphics Controller supports a full AGP implementation internally to
remain compatible with existing software and programming models. However,
since the engine is integrated, it enjoys a higher bandwidth and lower latency than
is possible with discrete solutions.
The controller of ENDAT-3400M supports 2 types of display: CRT and LVDS panel.
