Claim:
1. Digital circuitry configured to reference cells that comprise a scene, the digital circuitry comprising: a plurality of first input bitlines configured to receive a first value representative of an integer; a plurality of second input bitlines configured to receive a bitmap comprising a plurality of bits, the bitmap representative of cells comprising the scene, each bit corresponding to one of the cells of the scene, each bit being set (“dirty bit”) or cleared (“clean bit”) depending on whether or not a cell corresponding to said each bit contains at least a portion of a primitive object in the scene; a plurality of output bitlines; and digital circuits connected to the first input bitlines and the second input bitlines, the digital circuits configured to receive an integer i on the first input bitlines and a bitmap on the second input bitlines, the digital circuits configured to produce on the output bitlines a cell address of a given cell that corresponds to the i
