Display Pipes
The display pipe blends and synchronizes pixel data received from one or more display
planes and adds the timing of the display output device upon which the image is
displayed.
planes and adds the timing of the display output device upon which the image is
displayed.
The display pipes A and B operate independently of each other at the rate of one pixel
per clock. They can attach to any of the display interfaces.

Display Physical Interfaces
The display physical interfaces consist of output logic and pins that transmit the display
data to the associated encoding logic and send the data to the display device. These
interfaces can be subdivided into analog (VGA) and digital (DisplayPort*, embedded
DisplayPort*, DVI and HDMI*) interfaces.

12.4.1
Analog Display Physical Interface
The analog port provides a RGB signal output along with a HSYNC and VSYNC signal.
There is an associated Display Data Channel (DDC) signal pair dedicated to the analog
port. The intended target device is for a monitor with a VGA connector. Display devices
such as LCD panels with analog inputs may work satisfactorily but no functionality is
added to the signals to enhance that capability.
