Barrel shifter, modified Booths algorithm, multiplier design
The paper presents a design scheme to provide a faster implementation of multiplication of two signed or unsigned numbers. The proposed scheme uses modified booth's algorithm in conjunction with barrel shifters. It provides a uniform architecture which makes upgrading to a bigger multiplier much easier than other schemes. The verification of the proposed scheme is illustrated through implementation of 16x16 multiplier using ISIM simulator of Xilinx Design Suite ISE 14.2. The scheme is also mapped onto hardware using Xilinx Zynq 702 System on Chip. The performance is compared with existing schemes and it is found that the proposed scheme outperform in terms of delay.
