Video Processor Module
The Video Processor module contains a high performance
video back-end accelerator, a video/graphics Mixer/
Blender, and a Video Input Port (VIP), supporting two out-
put choices: CRT or TFT. The back-end accelerator func-
tions include horizontal and vertical scaling and filtering of
the video stream. The Mixer/Blender function includes
color space conversion, gamma correction, and mixing or
alpha blending the video and graphics streams.
