Abstract
A method and system for interface compression in a raster stage of a graphics processor. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitive at a first level in a coarse raster component to generate a plurality of tiles related to the graphics primitive. The method determines whether a window ID operation is required for the plurality of tiles. If the operation is required, a respective plurality of uncompressed coverage masks for the tiles are output from the coarse raster component to a fine raster component on a one coverage mask per clock cycle basis. If the operation is not required, a compressed coverage mask for the tiles is output in a single clock cycle. The tiles are subsequently rasterized at a second-level in the fine raster component to generate pixels related to the graphics primitive.
