color pattern.
Figure 5–16. Example of Splitting and Duplicating Color Patterns
In addition to fully sampled color patterns, the Color Plane Sequencer supports 4:2:2
subsampled data. To facilitate this support, you can configure the Color Plane
Sequencer with two color patterns in sequence, so that subsampled planes can be
specified individually.
When splitting subsampled planes from fully-sampled planes, the Avalon-ST Video
control packet for the subsampled video data packet can have its width value halved,
so that the subsampled planes can be processed by other MegaCore functions as if
fully sampled. This halving can be applied to control packets on port dout0 and port
dout1, or control packets on port dout0 only.
The only stream requirement imposed is that when two streams are being combined,
the video data packets must contain the same total number of pixels, and to make a
valid image, the packets must have the same dimensions. The Color Plane Sequencer
can process streams of pixel data of the types shown in
