2. FEATURES
VIDEO CAPABILITIES
Video capabilities are built around the CL-GD7556 high-performance 64-bit video and
graphics accelerated LCD/CRT controller, from Cirrus Logic.
The controller provides features such as:
GUI and true 64-bit accelerations
32-bit PCI V2.1 interface
Acceleration of MPEG-1
V-Port support for the implementation of built-in MPEG video playback, and external TV
tuner, video conferencing, and teleconferencing.
The video controller provides a high memory bandwidth, up to 80MHz, which allows the
board to support V-Port applications at a resolution of 1024x768.
Video capabilities are as follows:
Video memory: 2MB EDO 64-bit RAM
CRT display: 1280 x 1024 x 256, 1024 x 768 x 64K, 800 x 600 x 16M,
640 x 480 x 16M.
Flat panel: up to 1024 x 768 – 64K colors Dual-Panel, Dual-Drive, STN
and TFT panels
V-Port Interface: The V-port interfaces video data directly from the MPEG-1
decoder or an external video device through the J11 connector.
The video stream is transferred directly into the display
memory, bypassing the CPU.
The V-Port appears as a multimedia solution that requires no
external video processing hardware and additional display
memory. The V-port offers high-quality low-cost multimedia
options such as live-video preview and capture, TV-in-a-
window, hardware assisted MPEG and video conferencing.
The video controller provides all the signals necessary to drive flat-panel (1024x768 max.)
and CRT monitor simultaneously. It supports up to 16.8M colors in most VGA and video
formats.
The multimedia capabilities include acceleration of video playback, video capture, live-
video presentation and other video applications - all with continuous upscaling to
resolution up to 1024x768.
