Abstract: The present disclosure relates to methods and apparatus for display processing. The apparatus can determine at least one data parameter corresponding to each of a plurality of layers in a display frame. The apparatus can also calculate a model for the at least one data parameter corresponding to each of the plurality of layers. Additionally, the apparatus can modify the model for the at least one data parameter based on one or more application use cases of the display frame. Moreover, the apparatus can implement the modified model on each of the plurality of layers in the display frame. In some aspects, the apparatus can also determine one or more composition settings for each of the plurality of layers based on the modified model. The apparatus can also apply the one or more composition settings to each of the plurality of layers based on the modified model.

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 configured to identify an adjustment in one or more layers of a plurality of layers in a current frame compared to layers of a plurality of layers in a previous frame; to determine, upon identifying the adjustment in the one or more layers, a first resource allocation for each of the plurality of layers; to determine, after the determination of the first resource allocation begins, a second resource allocation for each of the plurality of layers; to initiate, upon determining the first resource allocation, an execution of the composition process for each layer in the current frame based on the first resource allocation; and to initiate, upon determining the second resource allocation, an execution of the composition process for each of the layer in at least one subsequent frame based on the second resource allocation.

Abstract: Methods, systems, and devices for adaptive display data transfer rate to reduce power consumption during partial frame composition are described. The method may include identifying a set of frames for display on a panel of the device, determining a starting line of an updating frame region of the set of frames in relation to a first pixel line of the panel, determining an ending line of the updating frame region of the set of frames in relation to the first pixel line of the panel, reducing a bus bandwidth vote based on the starting line of the updating frame region, or the ending line of the updating frame region, or a number of lines of the updating frame region, or any combination thereof, and transferring the lines of the updating frame region from a display processor unit to a panel memory at the reduced bus 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: The present disclosure relates to methods and apparatus for display processing. The apparatus can monitor a rendering time for each of a plurality of layers in a display frame. The apparatus can also determine whether a rendering time of one or more layers is greater than a maximum rendering time threshold. The apparatus can also adjust a rendering resolution of the one or more layers when the rendering time of the one or more layers is greater than the maximum rendering time threshold. Moreover, the apparatus can reduce the rendering resolution of the one or more layers when the rendering time of the one or more layers is greater than the maximum rendering time threshold. Also, the apparatus can increase the rendering resolution of the one or more layers when the rendering time of the one or more layers is less than a minimum rendering time threshold.

Abstract: The present disclosure relates to methods and apparatus for display processing. Aspects of the present disclosure can determine a refresh offset for at least one group of lines in a first display based on at least one group of lines in a second display. Aspects of the present disclosure can also apply the refresh offset for the at least one group of lines in the first display based on the at least one group of lines in the second display. Further, aspects of the present disclosure can adjust combined instantaneous bandwidth corresponding to each of the at least one group of lines in the first display and each of the at least one group of lines in the second display based on the applied refresh offset. Aspects of the present disclosure can also determine one or more overlapping layer regions based on the first display and the second display.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an example apparatus may include a first processing unit and a second processing unit. The first processing unit may be configured to cause the second processing unit to store a frame for display in a first memory region of the plurality of memory regions. The first processing unit may be configured to cause the second processing unit to store first cursor content in a second memory region. The first cursor content may be representative of a visible state of a cursor. The first processing unit may be configured to cause the second processing unit to store second cursor content in a third memory region. The second cursor content may be representative of a non-visible state of the cursor.
