Abstract
A processor for computer graphics calculations comprising an entire graphics engine in a single integrated circuit. The processor includes a transform mechanism adapted to compute transforms for the computer graphics calculations. The transform mechanism includes a transformation element adapted to compute transforms using a dot product operation. The transform mechanism of the processor also includes a perspective division element, a color unit for lighting calculations, a scaling element for multiplication operations, and a look-up table containing mathematical functions used by the computer graphics calculations. The processor also includes a raster unit coupled to the transform mechanism, a texture unit coupled to the raster unit, and a shader unit coupled to the texture unit.
