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 apparatus for display processing. The apparatus can calculate a bandwidth compression ratio (CR) for each of a plurality of tile rows in one or more layers in a frame, each of the one or more layers being associated with one or more regions in the frame. The apparatus can also determine a bandwidth CR for each of the one or more regions associated with each of the one or more layers based on the calculated bandwidth CR for the plurality of tile rows in the one or more layers. Additionally, the apparatus can determine a total bandwidth for the frame based on the determined bandwidth CR for each of the one or more regions associated with the one or more layers. The apparatus can also calculate a total bandwidth for each of the one or more regions.

Abstract: According to various aspects, just-in-time system bandwidth changes may be implemented in hardware to optimize power consumption and performance in an electronic device. More particularly, in a periodic system associated with an electronic device, a bandwidth for a next frame may be configured during a current frame via software operating on the electronic device. Hardware associated with the periodic system may issue a bandwidth change request for the next frame when a current time reaches a bandwidth increase threshold in response to actual processing time associated with the current frame finishing prior to the bandwidth increase threshold, which may be defined relative to a timer deadline that defines when the next frame starts to process.
