摘要： A three-dimensional (3D) graphics pipeline which processes pixels of sub-screens in the last stage (pixel rendering) in parallel and independently. The sub-screen tasks are stored in a list in a shared memory. The shared memory is accessed by a plurality of processing threads designated for pixel rendering. The processing threads seize and lock sub-screens tasks in an orderly manner and process the tasks to create the bit map for display on a screen. The tasks are created by dividing a display area having the vertex information superimposed thereon into M×N sub-screen tasks. Based on system profiling, M and N may be varied.

摘要： This disclosure describes a multi-stage tessellation technique for tessellating a curve during graphics rendering. In particular, a first tessellation stage tessellates the curve into a first set of line segments that each represents a portion of the curve. A second tessellation stage further tessellates the portion of the curve represented by each of the line segments of the first set into additional line segments that more finely represent the shape of the curve. In this manner, each portion of the curve that was represented by only one line segment after the first tessellation stage is represented by more than one line segment after the second tessellation stage. In some instances, more than two tessellation stages may be performed to tessellate the curve.
摘要翻译：本公开描述了用于在图形呈现期间细分曲线的多阶段细分技术。特别地，第一曲面细分阶段将曲线镶嵌成第一组线段，其分别代表曲线的一部分。第二曲面细分阶段进一步将由第一组的每个线段表示的曲线部分细分为更精细地表示曲线形状的附加线段。以这种方式，在第一曲面细分阶段之后仅由一个线段表示的曲线的每个部分在第二曲面细分阶段之后由多于一个线段表示。在一些情况下，可以执行多于两个镶嵌阶段以镶嵌曲线。

摘要： A device has a processor for processing a vertex processing stage, a sub-screen dividing stage and a pixel rendering stage of a three-dimensional (3D) graphics pipeline. The processor includes processing threads which balance the work load of the 3D graphics pipeline by prioritizing processing for the pixel rendering stage over other stages. Each processing thread, operating in parallel and independently, checks a level of tasks in a Task list of sub-screen tasks. If the level is below a threshold value, empty or the sub-screen tasks are all locked, the processing thread loops to the vertex processing stage. Otherwise, the processing thread processes a sub-screen task during the pixel rendering stage.

摘要： A graphics processing unit (GPU) may perform three-dimensional (3D) graphics processing in accordance with a 3D graphics pipeline using a first plurality of graphics processing hardware units of the GPU. The GPU may further perform a two-dimensional (2D) graphics operation using a second plurality of graphics processing hardware units of the GPU not used in performing the 3D graphics processing and one or more graphics processing hardware units of the first plurality of graphics processing hardware units of the GPU.
