  • Patent number: 12118653
    Abstract: A system, method, and computer program product are provided for reducing GPU load by programmatically controlling shading rates in computer graphics. GPU load may be reduced by applying different shading rates to different screen regions. By reading the depth buffer of previous frames and performing image processing, thresholds may be calculated that control the shading rates. The approach may be run on any platform that supports VRS hardware and primitive- or image-based VRS. The approach may be applied on a graphics driver installed on a client device, in a firmware layer between hardware and a driver, in a software layer between a driver and an application, or in hardware on the client device. The approach is flexible and adaptable and calculates and sets the variable rate shading based on the graphics generated by an application without requiring the application developer to manually set variable rate shading.

    Abstract: A video coding system generating candidates for Merge Mode with Motion Vector Difference (MMVD) with reduced resource usage is provided. The system receives data to be encoded or decoded as a current block of a current picture of a video. The system identifies multiple MMVD candidates for different offset positions based on a merge candidate of the current block. The system generates reference samples for the identified MMVD candidates. The system reconstructs the current block or encodes the current block into a bitstream by using the generated reference samples. The system processes the MMVD candidates in separate groups: a first group of vertical MMVD candidates and a second group of horizontal MMVD candidates. The system generates the reference samples for the identified MMVD candidates by applying a vertical filter to source reference samples of horizontal MMVD candidates and then applying a horizontal filter to outputs of the vertical filter.
