The Processor Graphics controller display pipe can be broken down into three 
components: 

• Display Planes
• Display Pipes
• DisplayPort and Intel

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 
display output device and delivers that data to a display pipe. This is clocked by the 
Core Display Clock.

Planes A and B are the main display planes and are associated with Pipes A and B 
respectively. The two display pipes are independent, allowing for support of two 
independent display streams. They are both double-buffered, which minimizes latency 
and improves visual quality.

Sprite A and Sprite B are planes optimized for video decode, and are associated with 
Planes A and B respectively. Sprite A and B are also double-buffered.

Cursors A and B are small, fixed-sized planes dedicated for mouse cursor acceleration, 
and are associated with Planes A and B respectively. These planes support resolutions 
up to 256 x 256 each.
