Fast Multiplication

The fast multiplication can be achieved in three general ways. The sequential multipliers sequentially generates the partial products and adds them with the previously stored partial products. In the second method, high speed parallel multipliers generate the partial products in parallel and adds them by a fast multi-operand adder. The third method corresponds to use …

Wallace and Dedda Multiplier Design

Chris Wallace┬áin 1964 gave some suggestions on fast multiplication. In order to achieve high speed without consuming extra hardware he suggested techniques. He proposes to use the basic HAs and FAs as basic elements for operand reduction. He applied operand reduction in parallel layers and achieve better speed. The steps are Obtain the partial products …
