AGP-BUS VGA Feature
The on-board built-in Graphic Controller is a highly integrated display control
device that incorporates a 64-bit 3D/2Dgraphic engine and video accelerator with
advanced DVD video and optional TV out capability. It provides a flexible and
high performance solution for graphics and video playback acceleration for various
color depth and resolution modes.
The onboard built-in VGA is a fully integrated CRT and TV 64-bit 2D/3D
Accelerator. The high performance graphics engine offers high speed 3D image
processing in full compliance and compatibility with IBM® VGA and VESA™
extended VGA. As an integrated controller, it allows unprecedented cost and
performance advantages by eliminating the need for an external frame buffer while
at the same time gaining local access to a larger amount of memory. Many
functions can now be eliminated that previously consumed large amounts of
bandwidth.
The onboard VGA equipped with a single-cycle 3D GUI Engine, pipelines 3D
rendering process architecture in hardware, providing real-time interactions with
solid 3D models in CAD/CAM, 3D modeling, and 3D games. It supports all key
3D rendering operations, including: Guard shading for smooth object surfaces,
texture mapping for realistic object textures, 16-bit hardware Z-buffering for fast
3D depth calculations, and Alpha Blending for transparency effects.
The onboard VGA 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. AGP operations can include direct access of the
system memory by the 2D/3D engine to provide increased texture memory.
To meet the requirements of a PC98 graphics adapter in a multimedia PC, the
onboard VGA controller supports planar video format for MPEG-1, MPEG-2, and
42
ENDAT-5701 and ENDAT-5901 All-In-One motherboard uses
DVD-video playback. The dual video playback is capable of overlaying windows
for videoconferencing and multimedia displays. By using an extended 16-bit
capture / ZV port the onboard VGA controller can support DTV resolution. This
port can operate as either an input for video capture or as an output for video
display. The onboard VGA controller is capable of supporting three simultaneous
displays: CRT (analog monitor), Flat Panel (digital monitor), and video (standard
television display), each with a different “window” or desktop.

LCD Flat Panel Feature
The on-board flat panel interface is designed to support industry standard TFT and
DSTN panels. The Flat Panel interface can also be used to drive external LVDS or
PanelLink™ transmitters.
The high performance VGA Controller provides full hardware level VGA
compatibility. At reset, the onboard flat panel is in hardware level VGA mode and
all of the standard VGA subsections (Display Controller, VGA Graphics Controller,
and Attribute Controller) are enabled.
The onboard flat panel supports LVDS and PanelLink™, providing a low voltage,
high speed, low EMI, serial DC-balanced differential data to the LCD panel.
