6.7.2
The VP receives the input video stream in either YUV
(4:2:2 or 4:2:0) or RGB (5:6:5) format. The VP has an inte-
grated color space converter to convert YUV data to RGB
data. The video clock must always be active (regardless of
the source of video input).
Either graphics, or graphics and video mixed (via color-
keying or alpha-blending) can be displayed. Mixing can be
performed in either the RGB or YUV domain.

For video input, integrated scaling and X and Y interpola-
tion enable real-time motion video output. The video path
of the VP also contains horizontal and vertical scaling hard-
ware, and an optional YUV-to-RGB color space converter.
This motion video acceleration circuitry is integrated into
the VP to improve video playback. By off-loading these
arithmetic-intensive tasks from the CPU, 30 frame-per-sec-
ond playback can be easily achieved, while keeping CPU
utilization to acceptable performance levels.
