Abstract: The power consumption of processor-based devices may be reduced by reducing the consumption of power during graphics processing. In some embodiments, the precision of pixel shading in parts of images where artifacts are less objectionable may be reduced. For example, in areas the user is not directly looking at, precision may be reduced to save power. At the same time, because a person is not focusing on those regions, even if usually perceptible artifacts occur because of the reduced precision, an overall pleasing depiction may be achieved.

Abstract: A mechanism is described for facilitating dynamic culling of composite objects producing not visible change in graphics images on computing devices. A method of embodiments, as described herein, includes identifying one or more objects of a plurality of objects of a frame for being potentially insignificant to be included in a subsequent frame, and applying one or more bounding boxes encompassing the one or more objects. The method may further include determining, basing on a vertex transformation, one or more minimum bounding rectangles corresponding to the one or more bounding boxes. The method may further include determining, based on rasterization rules, coverage of the one or more minimum bounding rectangles to one or more pixel centers of one or more pixels, and selecting a first object of the one or more objects to be included in the subsequent frame, if a first of the one or more corresponding minimum bounding rectangles touch or include a pixel center of a pixel.

Abstract: In position-only shading, two geometry pipes exist, a trimmed down version called the Cull Pipe and a full version called the Replay Pipe . Thus, the Cull Pipe executes the position shaders in parallel with the main application, but typically generates the critical results much faster as it fetches and shades only the position attribute of the vertices and avoids the rasterization as well as the rendering of pixels for the frame buffer. Furthermore, the Cull Pipe uses these critical results to compute visibility information for all the triangles whether they are culled or not. On the other hand, the Replay Pipe consumes the visibility information to skip the culled triangles and shades only the visible triangles that are finally passed to the rasterization phase. Together the two pipes can hide the long cull runs of discarded triangles and can complete the work faster in some embodiments.

Abstract translation: 在仅位置阴影下，存在两个几何管道，一个称为“Cull Pipe”的修剪版本以及称为Replay Pipe的完整版本。 因此，Cull管道与主应用程序并行执行位置着色器，但是通常会以更快的速度生成关键结果，因为它仅获取和仅阴影顶点的位置属性，并避免光栅化以及框架的像素渲染 缓冲。 此外，Cull管道使用这些关键结果来计算所有三角形的可见性信息，无论它们是否被淘汰。 另一方面，Replay管道消耗可见性信息来跳过被剔除的三角形，并仅遮蔽最终传递到光栅化阶段的可见三角形。 两个管道一起可以隐藏丢弃的三角形的长的剔除运行，并且在一些实施例中可以更快地完成工作。

Abstract: Embodiments provide for a graphics processing apparatus comprising render logic to detect rendering operations that will result in framebuffer having the same data as the initial clear color value and morphing such rendering operations to optimizations that are typically done for initial clearing of the framebuffer.

Abstract: The introduction of an "out-of-memory" marker in the sorted tile geometry sequence for a tile may aid in handling out-of-memory frames. This marker allows hardware to continue rendering using the original data stream instead of the sorted data stream. This enables use of the original data stream allows the system to continue rendering without requiring any driver intervention. During the visibility generation/sorting phase, the number of memory pages required for storing the data for a rendering pass is continuously tracked. This tracking includes tracking the pages that are required even if the hardware had not run out-of-memory. This information can be monitored by a graphics driver and the driver can provide more memory pages for the system to work at full efficiency.

Abstract: Apparatus, systems and methods for handling portrait mode oriented display surfaces without requiring expensive hardware in the display sub-system are disclosed. For example, an apparatus is disclosed such that the rendering of graphics data to the portrait mode display surfaces is redirected at rendering time such that there is no need for adding complicated hardware in the display part of the graphics adapter in order to handle conventional displays - all of which have no circuitry to deal with data natively stored in a portrait mode surface. Additionally, an apparatus to handle direct surface access of a surface through a surface lock which has already been rotated is already described. This can either be done by copying of surface data or by an optimized proposed apparatus which eliminates this copy. Other implementations are also disclosed.
