  • Decoupled shading pipeline
    Patent number: 11875453
    Abstract: In some embodiments, a given frame or picture may have different shading rates. In one embodiment in some areas of the frame or picture the shading rate may be less than once per pixel and in other places it may be once per pixel. Examples where the shading rate may be reduced include areas where there is motion and camera defocus, areas of peripheral blur, and in general, any case where the visibility is reduced anyway. The shading rate may be changed in a region, such as a shading quad, by changing the size of the region.

  • Hierarchical Z-culling (HiZ) optimization for texture-dependent discard operations
    Patent number: 10540808
    Abstract: Methods and apparatus relating to techniques for provision of hierarchical Z-Culling (HiZ) optimization for texture-dependent discard operations are described. In an embodiment, a processor performs one or more operations (such as HiZ or Hierarchical Stencil test) on depth data of an image tile in response to a determination that texture space bounds of the image tile is fully opaque. The processor performs the one or more operations regardless of whether a discard operation is enabled. Other embodiments are also disclosed and claimed.

  • Reducing power consumption during graphics rendering
    Patent number: 10466769
    Abstract: In accordance with some embodiments, the knowledge that a capped frame time is used can be exploited to reduce power consumption. Generally a capped frame time is a pre-allocated amount of time to apply power for rendering in graphics processing. Generally the frame time involves the application of power and some down time in which only idle power is applied pending the next frame time. By making better use of that down time, power consumption reductions can be achieved in some embodiments.

  • Minimum/maximum and bitwise and/or based coarse stencil test
    Patent number: 10453170
    Abstract: Methods and apparatus relating to techniques for provision of minimum or maximum and bitwise logic AND or logic OR based coarse stencil tests are described. In an embodiment, metadata (corresponding to a plurality of pixels) is stored in memory. One or more operations are performed on the metadata to generate a stencil result. The one or more operations comprise a bitwise intersection operation or a bitwise union operation and/or a minimum operation or maximum operation. Other embodiments are also disclosed and claimed.
