2-62Service GuideThe display system can independently place either RGB or YUV data from anywhere in display
memory into an on-screen window which can be any size and located at any pixel boundary (YW
data is converted to RGB on-the-fly on output). Non-rectangular windows are supported via color
keying. The data can be fractionally zoomed on output up to 8x to fit the onscreen window and can
be horizontally and vertically interpolated. Interlaced and non-interlaced data are supported in both
capture and...

Major Chips Description2-63The 64-bit wide memory configurations have double the memory
bandwidth of the 32-bit wide configurations.
The figure below shows the display memory configurations using and external STN-DD buffer:· Some of the 32-bit configurations allow an additional 256K x 16
device to be used for an external 16-bit wide STN-DD buffer, as
shown above.
· The 65555 supports both video capture/playback and external
STN-DD buffer at the same time
