  • Publication number: 20220067875
    Abstract: Embodiments described herein are generally directed to conservative rasterization pipeline configurations that allow EarlyZ to be enabled for conservative rasterization. An embodiment of a method includes a conservative rasterizer receiving a primitive to be rasterized. Based on vertices of the primitive, the rasterizer creates a pixel location stream and inner coverage data, indicative of whether the corresponding pixel is fully covered by the primitive or partially covered by the primitive, for each pixel within the pixel location stream. Based on the inner coverage data, pixels of the pixel location stream are grouped into a first group including those of the pixels that are fully covered by the primitive and a second group including those of pixels that are partially covered by the primitive. Separate pixel shader threads are then launched by the rasterizer for blocks of pixels of the first group and blocks of pixels of the second group.

  • Patent number: 11263720
    Abstract: A control surface tracks an individual cacheline in the original surface for frequent data values. If so, control surface bits are set. When reading a cacheline from memory, first the control surface bits are read. If they happen to be set, then the original memory read is skipped altogether and instead the bits from the control surface provide the value for the entire cacheline.

  • Patent number: 11252370
    Abstract: Systems, apparatuses and methods may provide for technology that determines a frame rate of video content, sets a blend amount parameter based on the frame rate, and temporally anti-aliases the video content based on the blend amount parameter. Additionally, the technology may detect a coarse pixel (CP) shading condition with respect to one or more frames in the video content and select, in response to the CP shading condition, a per frame jitter pattern that jitters across pixels, wherein the video content is temporally anti-aliased based on the per frame jitter pattern. The CP shading condition may also cause the technology to apply a gradient to a plurality of color planes on a per color plane basis and discard pixel level samples associated with a CP if all mip data corresponding to the CP is transparent or shadowed out.

    Abstract: One embodiment provides a graphics processor comprising a hardware graphics rendering pipeline configured to perform multisample anti-aliasing, the hardware graphics rendering pipeline including pixel processing logic to determine that each sample location of a pixel of a multisample surface is associated with a clear value and resolve a color value for the pixel to a non-multisample surface via a write of metadata to indicate that the pixel has the clear value. The resolve can be a stenciled resolve that automatically bypasses execution of a pixel shader for pixels having clear color data.
