    Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may receive a plurality of pixels associated with a first color space including a plurality of first color channels, at least one first color channel of the plurality of first color channels being a first compressed channel. The apparatus may also decompress the at least one first color channel of the plurality of first color channels, the at least one first color channel being decompressed from the first compressed channel to a first decompressed channel. Further, the apparatus may perform a color space conversion of the first color space associated with the plurality of pixels, such that the plurality of first color channels is converted to a plurality of second color channels, the plurality of second color channels being associated with a second color space for the plurality of pixels.

    Abstract: Methods and devices for managing data flows for concurrent multimedia applications executing on a device including a SoC, in response to determining that a temperature or power consumption exceeds a threshold are disclosed. A lowest priority data flow may be identified. A data flow path associated with the identified lowest priority data flow may be traced. A multimedia parameter of any hardware module along the data flow path may be reduced. When the temperature or power consumption no longer exceeds the threshold, a highest priority data flow among the multimedia applications that has had the multimedia parameter reduced may be identified. A data flow path for a data flow associated with the identified highest priority data flow may be traced. The multimedia parameter may be restored to an original value along the traced data flow path for the data flow associated with the identified highest priority data flow.

    Abstract: Scheduling image composition in a processor based on overlapping of an image composition process and image scan-out operation for displaying an image is disclosed. The processor is configured to periodically schedule a composition process to generate composition passes on the received eyebuffers to generate a display-corrected image for scan-out to a display device. To reduce the motion-to-photon latency, the processor is configured to delay scheduling of the composition process to be closer in time to the scan-out deadline such that there is an overlap in execution of the composition process at the scan-out deadline and image scan-out operation. The scheduling of the composition process can be delayed to only generate a desired number of display lines for the display-corrected image before the scan-out deadline such that lines of the display-corrected image can continue to be available faster than needed for scanning out by the image scan-out operation without scan-out delay.

    Abstract: Aspects of this disclosure relate to a device for generating image content that includes a memory and processing circuitry coupled to the memory. The processing circuitry is configured to determine a dithered fractional VRS value for a core block based on a dithering factor for the core block and a fractional VRS value for the core block and determine a dithered fractional shading rate based on the dithered fractional VRS value. The processing circuitry is further configured to render the image based on the dithered fractional shading rate.
