Abstract: In some aspects, the present disclosure provides a method for bandgap voting. In some configurations, the method includes receiving, at a hardware voting component associated with a destination subsystem, metadata for each of a plurality of compressed display tiles, wherein for each of the plurality of compressed display tiles the metadata indicates an amount of compression of the compressed display tile. In some configurations, the method includes dividing the plurality of compressed display tiles into a plurality of sets of compressed display tiles. In some configurations, for each of the plurality of sets of compressed display tiles, the method includes determining a desired bandwidth for communicating the set of compressed display tiles over a bus, and receiving the set of compressed display tiles at the destination subsystem over the bus at an actual bandwidth that is based on the desired bandwidth.

Abstract: The present disclosure relates to methods and devices for video or frame processing including an apparatus, e.g., a video or frame processor. In some aspects, the apparatus may receive a video stream including a plurality of frames, each of the plurality of frames including luminance information. The apparatus may also perform a histogram analysis on the luminance information for each of the plurality of frames. Additionally, the apparatus may determine whether a difference between the luminance information for each of the plurality of frames and a current luminance distribution is greater than a perceptual threshold. The apparatus may also calculate an updated tone mapping configuration based on the luminance information for a frame when the difference between the luminance information for the frame and the current luminance distribution is greater than the perceptual threshold.
