Note
Double Buffer Enable
This bit is used in conjunction with the Window Data Type bit (REG[36h] bit 7) and con-
trols the Double Buffer architecture. Double buffering is intended to prevent visual tearing
when updating the display from streaming input sources. This bit must be set before the
window data is written, as the window coordinates will be latched internally to be used by
the display pipe during display cycles.
When this bit = 0, the double buffer architecture is disabled.
When this bit =1, the double buffer architecture is enabled. This feature is only available if
the memory size resulting from the display size and color depth will fit within the 1/2 the
allowable size for the display buffer.
For a summary of Window Data Type / Double Buffer options, see Table 10-11: “Window
Data Type / Buffer Selection,” on page 60.
While double buffering is enabled, the window coordinates should not be modified.
Only one window can be double-buffered. All other windows are single buffered.
