Parallel multiplication using fast sorting networks
A recent paper describes the use of Svoboda's binary counter in the construction of fast parallel multipliers. The resulting approach was shown to he faster than the conventional Dadda multiplier when the wordlength N was small. Unfortunately, the growth in the number of gates of that method was O(N-3) and the speed was O(N). In this paper, Batcher's bitonic sorting network and other efficient networks replace the Svoboda counter. The asymptotic growth rate in gates of these new methods is O(N-2 log(2) N), and the speed is O(log(2) N).
