Processor 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.
