Abstract: The systems, apparatuses and methods may provide a way to adaptively process and aggressively cull geometry data. Systems, apparatuses and methods may provide for processing, by a positional only shading pipeline (POSH), geometry data including surface triangles for a digital representation of a scene. More particularly, systems, apparatuses and methods may provide a way to identify surface triangles in one or more exclusion zones and non-exclusion zones, and cull surface triangles in one or more exclusion zones.

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: An embodiment of a graphics command coordinator apparatus may include a commonality identifier to identify a commonality between a first graphics command corresponding to a first frame and a second graphics command corresponding to a second frame, a commonality analyzer communicatively coupled to the commonality identifier to determine if the first graphics command and the second graphics command can be processed together based on the commonality identified by the commonality identifier, and a commonality indicator communicatively coupled to the commonality analyzer to provide an indication that the first graphics command and the second graphics command are to be processed together. Other embodiments are disclosed and claimed.

Abstract: Apparatus and method for stack throttling. For example, one embodiment of an apparatus comprises: execution circuitry comprising a plurality of functional units to execute a plurality of ray shaders and generate a plurality of primary rays and a corresponding plurality of ray messages; a first in first out (FIFO) buffer to queue the ray messages generated by the EUs; a cache to store one or more of the plurality of primary rays; a memory-backed stack to store a first subset of the plurality of ray messages in a corresponding plurality of entries; memory-backed stack management circuitry to either store a second subset of the plurality of ray messages to the memory-backed stack, or to temporarily store the one or more the second subset of the plurality of ray messages to a memory subsystem based, at least in part, on a number of entries currently occupied by ray messages in the memory-backed stack; and ray traversal circuitry to read a next ray message from the memory-backed stack, retrieve a next primary ray identified by the ray message from the cache or a memory subsystem, and perform traversal operations on the next primary ray.

Abstract: Examples are described here that can be used to enable a main routine to request subroutines or other related code to be executed with other instantiations of the same subroutine or other related code for parallel execution. A sorting unit can be used to accumulate requests to execute instantiations of the subroutine. The sorting unit can request execution of a number of multiple instantiations of the subroutine corresponding to a number of lanes in a SIMD unit. A call stack can be used to share information to be accessed by a main routine after execution of the subroutine completes.

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.
