19. Display Unit (DU)

19.4.1
The display unit (DU) executes window displays with up to a maximum of six window layers.
Each of these windows is called a "plane", and the order of stacking of the planes can be set
arbitrarily. For each plane, display can be turned on and off, and the display data format (8
bits/pixel, 16 bits/pixel, ARGB, YC), blending functions, and other settings can be changed
independently.
Each plane has a double-buffer configuration, so that smooth display is possible.
Note: In cases of high-resolution display, the unified memory traffic volume may be

considerable depending on the number of combined planes and display size, and
constraints may arise owing to the traffic volume; but there are no constraints on display
functions.
