  • Method and system for a speedup of a bit multiplier
    Patent number: 6421699
    Abstract: A method and system is provided which overlaps the process of partial product reduction and the final adder in both higher- and lower-order bits when performing multiplication. The method and system reduces the number of left-over bits such that the final addition on these bits requires fewer logic stages to complete its process thereby reducing the propagation delay.
