SoC Graphics Display
The Processor Graphics controller display pipe can be broken down into three
components:
components:
•
Display Planes
•
Display Pipes
•
Display Physical Interfaces
A display plane is a single displayed surface in memory and contains one image
(desktop, cursor, overlay). It is the portion of the display hardware logic that defines
the format and location of a rectangular region of memory that can be displayed on a
display output device and delivers that data to a display pipe. This is clocked by the
Core Display Clock.

14.2.2
Video Sprite Planes A, B, C and D
Video Sprite Planes A, B, C and D are planes optimized for video decode. Planes A and
B are associated with Pipe A and Planes C and D are associated with Pipe B.
B are associated with Pipe A and Planes C and D are associated with Pipe B.
14.2.3
Cursors A and B
Cursors A and B are small, fixed-sized planes dedicated for mouse cursor acceleration,
and are associated with Planes A and B respectively.
