Abstract: Described herein is a data processing system comprising a memory device to store a multisample render target and a general-purpose graphics processor comprising a multisample antialiasing compressor and a multisample render cache. The multisample render target can store color data for a set of sample locations of each pixel in a set of pixels. The multisample antialiasing compressor can apply multisample antialiasing compression to color data generated for the set of sample locations of a first pixel in the set of pixels. The multisample render cache can store color data generated for the set of sample locations of the first pixel in the set of pixels. Color data evicted from the multisample render cache is stored to the multisample render target.

Abstract: Systems, apparatuses and methods may provide away to render edges of an object defined by multiple tessellation triangles. More particularly, systems, apparatuses and methods may provide a way to perform anti-aliasing at the edges of the object based on a coarse pixel rate, where the coarse pixels may be based on a coarse Z value indicate a resolution or granularity of detail of the coarse pixel. The systems, apparatuses and methods may use a shader dispatch engine to dispatch raster rules to a pixel shader to direct the pixel shader to include, in a tile and/or tessellation triangle, one more finer coarse pixels based on a percent of coverage provided by a finer coarse pixel of a tessellation triangle at or along the edge of the object.
