Abstract: Paper shows the implementation of improved Radix 4 Booth multiplier in VHDL software. Booth multiplication allows for faster, smaller multiplication circuits through encoding the signed numbers to its 2’s complement and which is also one of the standard technique used in chip designing. The algorithm reduces the number of partial product to half over “long multiplication” techniques. Proposed optimized Radix-4 Booth’s multiplier modify the way it does the addition of partial products. All these multiplier designs were modelled in Verilog HDL. Paper presents comparative analysis of Radix-4 booth multiplier with different multiplier techniques. Comparison shows optimized Radix-4 multiplier is superior from other multipliers in terms of various constraints.
