US 2024/0203376 A1 · EFFICIENTLY PROCESSING MULTIPLE NON-OVERLAPPING LAYER IMAGES IN DISPLAY PROCESSING UNITS

Abstract

Efficiently processing multiple non-overlapping layer images in display processing units is disclosed herein. In this regard, in some exemplary aspects, a display processing unit comprising a plurality of memory access pipeline circuits and a layer mixer circuit is provided. For each non-overlapping layer image of a plurality of non-overlapping layer images, a memory access pipeline circuit obtains image configuration data for the non-overlapping layer image, and fetches the non-overlapping layer image from an image data storage device based on the image configuration data. The memory access pipeline circuit then outputs each pixel of the non-overlapping layer image as part of an intermediate preblend image data stream based on the image configuration data. The layer mixer circuit blends the intermediate preblend image data stream and a background layer image data stream comprising a background layer image as a display data stream, and outputs the display data stream to a display device.
