| Summary: | As the advance of VLSI technology, low power design has become an important topic in
VLSI design. This project is to design a low power multiplier implemented in mentor
graphic tools. Low power multipliers are developed through minimizing switching
activities of partial product using the radix 4 booth algorithm. Before computation for two input data, the one with a smaller effective dynamic range is processed to generate booth codes, thereby increasing the probability that the partial products become zero. By employing the dynamic-range determination unit to control input data paths, the multiplier with a column-based adder tree of compressors or counters is designed. The proposed 16x16-bit multiplier reduces power consumed by the conventional multiplier. The proposed multiplier design will try to reduce the total power consumption by 20% - 30% when compared with other multiplier. The multipliers proposed herein can be broadly used in various media processing to yield low-power consumption at limited hardware cost. |
