Abstract
Inventive aspects include a binning unit for coarse depth culling during binning of pixel geometries. The binning unit includes a rasterizer to receive primitives, and generates pixel coverage information and depth information. The binning unit includes one or more local culling stages to perform local culling within a window of primitives. The local culling unit outputs a set of surviving coverage and surviving depth information. The binning unit includes one or more global culling stages to use the set of the surviving coverage and the surviving depth information to further cull based on an entirety of previously received coverage information and depth information.
