Abstract
In a graphics pipeline of a graphics processor, a method for caching pixel data. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitive to generate a plurality of tiles of pixels related to the graphics primitive. A subpixel sample group related to each of the plurality of tiles is determined. The plurality of tiles and the corresponding plurality of subpixel sample groups are stored into a frame buffer memory. A set of tiles and a set of corresponding subpixel sample groups from the frame buffer memory are stored in a rasterization cache, wherein the rasterization cache is configured for access by the raster stage to enable a subpixel anti-aliasing operation.
