Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine a composition of one or more layers for display at the display client. The processor is further configured to select a video mode or a command mode as a selected mode, based on the determined composition. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.

Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine one or more user input events based on user interaction data. The processor is further configured to select a video mode or a command mode as a selected mode, for operating the display processor, using the quantity of touch events. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.

Abstract: Techniques are described for reducing the number of fetches performed when a background layer (e.g., letter or pillar box) to be displayed is of a constant fill color. One or more processors (e.g., a display processor) may be configured to detect that a background layer is of a constant fill color. If so, rather than fetching the background layer from memory, the one or more processors may be configured to generate the constant fill color for the background layer. In doing so, there may be a reduction in the number of memory fetches performed, as the constant fill background layer is not fetched or is only partially fetched. This may reduce memory fetch operations (as only the video layer is fetched) and therefore power savings (e.g., battery usage) at memory and bus interfaces, decreased use of the bandwidth at the bus and memory, and decreased processor usage.
