7.4.1.4 Pixel Format
The pixel format has the name 420PL12YUV8. This consists of a single plane of luma
(Y) and a second plane consisting of interleaved Cr/Cb (V/U) components. For
420PL12YUV8, the number of chroma samples is a quarter of the quantity of luma
samples—half as many vertically, half as many horizontally. See Table 74 and Table 75
for pixel formats.
7.5 Display
The Display Controller provides the 2D graphics functionalities for the display pipeline.
The Display Controller converts a set of source images or surfaces, and merges them
and delivers them at the proper timing to output interfaces that are connected to the
