The Video Processor (VP) module provides a high-perfor-
mance, low-power CRT/TFT display or video output inter-
face. There are three main functions contained within the
VP: the Video Processor, the TFT controller, and the video
output port (VOP). The scaling, filtering, and color space
conversion algorithms implemented in the VP are of much
higher quality than those used in software-only video play-
back systems. The VP is capable of delivering high-resolu-
tion and true-color graphics. It can also overlay or blend a
scaled true-color video image on the graphic background.
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 Video Processor to improve video playback. By off-
loading these arithmetic-intensive tasks from the proces-
sor, 30 frame-per-second playback can be easily achieved,
while keeping processor utilization to acceptable perfor-
mance levels. The graphics and video path is illustrated in
Figure 6-23 on page 387.
