• Manufacturer Part Number: SC2200
• Description: Thin Client On a Chip
• Manufacturer: NSC [National Semiconductor]

Revision 3.0
6.0
The Video Processor module contains a high performance
video
Mixer/Blender, a Video Input Port (VIP), supporting two
output choices: CRT or TFT. The back-end accelerator
functions include horizontal and vertical scaling and filter-
ing of the video stream. The Mixer/Blender function
includes color space conversion, gamma correction, and
mixing or alpha blending the video and graphics streams.
