Abstract
In embodiments described herein, graphics hardware is described to reduce the number of wasted clock cycles expended during rasterization and performs coverage test iteration in a cache coherent manner. An exemplary embodiment comprises block selection logic to select an initial block of pixels associated with edges of a primitive and edge determination logic to analyze the initial block of pixels to determine a set of fully covered quadrants of the initial block of pixels and analyze a block of pixels adjacent to the initial block of pixels to determine whether the block of adjacent pixels is void.
