  • Carry look-ahead adder having a reduced area
    Publication number: 20050091299
    Abstract: The present invention relates to a carry look-ahead adder. The carry look-ahead adder is configured in 4-bit units in general. Each 4-bt carry look-ahead adder is combined with a carry look-ahead generating unit to constitute a carry look-ahead adder that can process input signals of larger size. The carry look-ahead adder according to the embodiment of the present invention calculates carry of each bit sequentially not by using any carry generation function or any carry propagation function but by using previous bit when generating an internal carry in the adder, so that propagation delay is allowed a little but the logic gate circuit can be simplified.
