    A Close Look Towards Modified Booth's Algorithm with BKS Process

    In this paper, the authors are remodeling of modified Booth's algorithm, where shift three at a time. The result shows that classical concept of single shift multiplication algorithms are to be revised with a multiple number of shifts. The observation is that in general the complexity is N/3, which is...
