A new algorithm for design of the Booth-based multiplier unit
Chen Zhong-ming · Journal of Hefei University of Technology · 2006
High-radix Booth is of great importance for speeding up multiplying by reducing the number of partial products,but it also adds great burdens on the adder of the multiplier in the aspects of timing and area.On the basis of analyzing the theory of multiplication operation in digital circuits and the principle of partial products shrinking,a radix-x Booth algorithm is proposed.It can achieve speeding up multiplying dynamically without burdening the adder,and it is better than a 32 bit mantissa radix-8 floating point multiplier in both area and timing.
