Abstract: In an embodiment, a display pipe is configured to composite one or more frames of images and/or video sequences to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame to memory responsive to detecting static content in the output frames is detected. The display pipe may also be configured to read the compressed frame from memory for display instead of reading the frames for compositing and display. In some embodiments, the display pipe may include an idle screen detect circuit configured to monitor the operation of the display pipe and/or the output frames to detect the static content.
