A cache stores data for use in rasterizing graphics data. The size of the cache is equal to a selected tile size. A processor performs the rasterization of the graphics image by subdividing the graphics image into a plurality of sub-blocks. The sub-blocks are processed, based on a block processing order, by further subdivision of the sub-blocks into tiles for those sub-blocks that have graphics image data. The tiles have a size equal to the selected tile size. Data, associated with a tile, is loaded into the cache, and the cache data is utilized to generate pixels for the associated tile of the graphics image.
