Booth Multiplier: The Systematic Study

Abstract

Booth multiplier plays a major role in digital integrated circuits. Multipliers are used for arithmetic operations. There are several digital multipliers used in different applications in VLSI. This paper reviews different types of booth multipliers, comparison, Advantages, drawbacks and extensions, the basic architecture of the booth multiplier and its algorithm. The power consumption, delay time and area occupied by the chip, also better performance are taken into the consideration, we can justify the efficiency of multipliers and remodeling the modules in multipliers reduces partial product generation in booth encoder. Wallace booth multiplier uses modified encoder to overcome the drawback that occurred in 2009 paper and drawbacks in array multiplier are overcome by Wallace booth multiplier. We observed that modifying the modules in booth multiplier we can reduce power consumption and increase scalability.
