ACCELLERATED START TILE SEARCH

摘要

An accelerated start tile search is provided to use necessary graphics rendering hardware and a clock cycle consumed in the rendering hardware efficiently, thereby certainly creating pixels suitable for a created window clip video. A method for accelerated start tile rasterization comprises the following steps of: defining a window(202) for clipping a created image; receiving a graphics primitive for rasterization in the raster stage of a graphics processor; performing a binary search associated with the window to determine a start tile including at least a partial coverage of the graphics primitive and plural pixels; and rasterizing the graphics primitive by creating plural neighboring tiles having at least the partial coverage of the graphics primitive on the basis of the start tile.
