Video Processor Module7

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.
