Abstract
A data processing system uses the same structure and hardware to implement either a general purpose multiplier or arithmetic operations associated with the least-mean-squares (LMS) algorithm. Multiplier and adder circuits are time-shared to perform the myriad functions. In one form, further modified Booth's algorithm is utilized so that an output product of two binary input numbers may be quickly formed by executing a series of multiplications and accumulations. The operation is pipelined for continuous processing activity.
