Summary:1. Field of Invention An energy saving multiplication device and its method is disclosed. The multiplication device includes a dynamic range determination unit, a Booth encoding/decoding unit and a counter array. The dynamic range determination unit determines dynamic ranges of the numerical values to be multiplied together and outputs after processing according to the dynamic-range size relation of the input data. The Booth encoding/decoding unit couples to the dynamic range determination unit. The counter array couples to the Booth encoding/decoding unit for accumulating the partial products to obtain the products of the input data.
