Pixel Halved Window

Note

Window Pixel Sizing bits [1:0]

These bits must be set before the window being written. The window coordinates will be

latched internally to be used by the display pipe during display cycles.

Only 1 active window can be pixel doubled. The pixel doubling design uses horizontal

and vertical averaging for smooth doubling.

The sizing is performed with respect to the top left corner

To turn off pixel doubling for a currently pixel doubled window, either:

1. Overwrite any part of the pixel doubled window with a new window.

2. Write a new pixel doubled window.
