Abstract
A blending system and method for blending source pixel color values with destination pixel color values in a computer graphics system according to a source alpha value includes a resolution increasing circuit that increases a number of bits in the source alpha value to produce an increased resolution source alpha value. Blending hardware implements a blending routine according to a blending equation to blend the source pixel color values with the destination pixel color values using the increased resolution source alpha value. In one embodiment, the resolution increasing circuit includes a squaring circuit that squares the source alpha value.
