摘要： This disclosure describes techniques for handling divergent thread conditions in a multi-threaded processing system. In some examples, a control flow unit may obtain a control flow instruction identified by a program counter value stored in a program counter register. The control flow instruction may include a target value indicative of a target program counter value for the control flow instruction. The control flow unit may select one of the target program counter value and a minimum resume counter value as a value to load into the program counter register. The minimum resume counter value may be indicative of a smallest resume counter value from a set of one or more resume counter values associated with one or more inactive threads. Each of the one or more resume counter values may be indicative of a program counter value at which a respective inactive thread should be activated.

摘要： This disclosure describes techniques for removing vertex points during two-dimensional (2D) graphics rendering using three-dimensional (3D) graphics hardware. In accordance with the described techniques one or more vertex points may be removed during 2D graphics rendering using 3D graphics hardware. For example, the techniques may remove redundant vertex points in the display coordinate space by discarding vertex points that have the substantially same positional coordinates in the display coordinate space as a previous vertex point. Alternatively or additionally, the techniques may remove excess vertex points that lie in a straight line. Removing the redundant vertex points or vertex points that lie in a straight line allow for more efficient utilization of the hardware resources of the GPU and increase the speed at which the GPU renders the image for display.
摘要翻译：本公开描述了使用三维（3D）图形硬件在二维（2D）图形渲染期间去除顶点的技术。根据描述的技术，可以使用3D图形硬件在2D图形渲染期间移除一个或多个顶点。例如，这些技术可以通过丢弃在显示坐标空间中具有与先前顶点相同的位置坐标的顶点来去除显示坐标空间中的冗余顶点。或者或另外，这些技术可以去除位于直线上的多余顶点。去除位于直线上的冗余顶点或顶点可以更有效地利用GPU的硬件资源，并提高GPU渲染图像以进行显示的速度。

摘要： The system includes a bounds primitive rasterizer that rasterizes a bounds primitive into a selection of primitive pixels. The selection of primitive pixels bounds a shape to be rendered to a screen. The system also includes a pixel mask generator that generates a pixel mask for the shape. The pixel mask includes mask pixels that each corresponds to one of the primitive pixels. A mask pixel is a covered pixel when the shape covers at least a threshold portion of the mask pixel and is an uncovered pixel when the shape does not cover the mask pixel. The system also includes a pixel screener configured to retain primitive pixels that correspond to covered mask pixels and to discard primitive pixels that correspond to uncovered mask pixels.

摘要： A method for evaluating the depth of a pixel in a scene, the scene enclosed in a view volume, the scene to be rendered from a camera position, the view volume having a near and a far plane, includes calculating a depth value for a pixel in the scene, the depth value being generated by a depth function of view distance within the view volume from the camera position, and storing the depth value in a floating-point format, the floating-point format including a mantissa and exponent, where, as the distance of the pixel to the far plane decreases, the absolute magnitude of the depth value generated by the depth function approaches the minimum non-negative number representable by the floating-point format.

摘要： In general, aspects of this disclosure describe example techniques for efficient usage of the fixed data rate processing of a graphics processing unit (GPU) for a variable data rate processing. For example, the GPU may be coupled to a pixel value processing unit that receives pixel values for pixels in an image processed by the GPU. The pixel value processing unit may determine whether the pixel values are for pixels that require further processing, and store the pixel values for the pixels that are required for further processing in a buffer.

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.
