  • Patent number: 10915982
    Abstract: A graphics processing unit (GPU) is provided. The GPU includes a command stream parser (CSP). The CSP receives a command list from a display driver and parses commands in the command list to determine a rendering mode of the GPU and perform a graphics rendering pipeline for graphics processing according to the rendering mode. When the CSP determines that at least a specific CSP command is not included in the command list, the CSP determines that the rendering mode is a first rendering mode. When the CSP determines that the specific CSP command is included in the command list, the CSP determines that the rendering mode is a second rendering mode. In the second rendering mode, the CSP divides a rendering target into tiles, obtains first drawing commands from the command list according to the specific CSP command, and executes the first drawing commands for each tile.

  • Patent number: 10628911
    Abstract: A graphics processing unit (GPU) is provided. The GPU includes a command stream parser (CSP) including a profiling unit used to provide performance statistics data for the GPU to determine a rendering mode of the GPU, wherein the rendering mode includes a first rendering mode and a second rendering mode for performing a graphics rendering pipeline for graphics processing. The profiling unit calculates drawing time of frames and the number of objects in the frames when the GPU operates in the first rendering mode, and determines whether the operation of the GPU is switched to the second rendering mode according to the calculated drawing time and the number of objects; when determining that the calculated drawing time and the number of objects are less than their respective thresholds, the CSP causes the operation of the GPU to switch from the first rendering mode to the second rendering mode.
