TILE BASED PRECISION RASTERIZATION IN A GRAPHICS PIPELINE

摘要

A tile-based precision rasterization in a graphic pipeline is provided to scale a screen at a regular ratio when a graphics program needs additional capabilities without causing an increase of power consumption and the reduction of productivity. A method for tile-based precision rasterization comprises the following steps of: receiving a graphics primitive for rasterization in the raster stage of a graphics processor; rasterizing the graphics primitive at a first level precision to generate plural tiles of pixels(501); rasterizing the tiles at a second level precision to generate covered pixels(502); and outputting the covered pixels to perform a render operation in the following stage of the graphics processor(503).
