Feature
ENDAT-9401F/H provides an integrated graphics (Intel® Graphics Media
Accelerator 950) accelerator delivering cost competitive 3D, 2D, and video
capabilities. It contains an extensive set of instructions for 3D operations, BLT
(Block Level Transfers) and Stretch BLT operations, motion compensation, overlay,
and display control. ENDAT-9401F/H video engines support video conferencing
and other video applications. Instead of a dedicated local graphics memory
interface, ENDAT-9401F/H applies UMA configuration for optimal memory
utilization and performance that deliver 3D graphics with sharp images, fast
rendering, smooth motion and extreme detail.
The Intel® 945GM Express chipset's low power design enables up to 28% less
average power consumption compared to previous generations. Featuring the
Intel® Graphics Media Accelerator 950, the Intel 945GM Express chipset delivers
up to 2 x improvements in graphics performance over the previous generation
chipset. The Intel® 945GM Express chipset enables up to 25% higher data transfer
rate compared to the previous generation bus speed.
ENDAT-9401F/H applies Intel® DVMT 3.0 for optimum the system utilization via
system chipset. DVMT is a concept be applied in the Intel® 945GM chipset wherein
the optimum amount of memory is dynamically allocated and de-allocated as
needed for balanced graphics and system performance, through Intel® Direct AGP
and a highly efficient memory utilization scheme.
The on-board INTEL® GMA950 Graphic 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-9401F/H supports 3 types of display: CRT, DVI and LVDS
panel.

4-2. LVDS Panel Feature
(optional)
The on-board graphic controller supports industry standard LCD panel, LVDS
interface only, with 1 channel (18 or 24) and 2 channels (36 or 48bit) data width.
LVDS interface provides low voltage, high speed and low EMI serial DC-balanced
differential data via optional onboard LVDS.
The flat panel interface provides or supports following functions for various panels:
-
Generates LVDS flat panel channels like clock and data channel.
-
Generates different video data formats to directly drive different types of
panels (18, 24, 36 or 48bit)
-
Wide screen resolution as 16:9 or 16:10.
-
Vertical and horizontal expansion of video displays to LCD panel resolution
-
Vertical and horizontal centering
- Panel

Please note that the default setting is with “CRT”. If the LCD display features is
required, the setting will need to be revised in the system BIOS setting: “CRT+EFP”
under “Advanced Chipset Features” unless clients specified the display type while order.
