Comparative Analysis of 32-Bit and 64-Bit Array Multiplier and Modified Booth Multiplier
Abstract - Multipliers are integral part of digital signal processors. Their improved performance is the main factor in the advancement of DSP . This paper presents a comparative analysis of 32-bit and 64-bit array multiplier and modified booth multiplier respectively on basis of various performance parameters in term of power, and area. Implementation of both multipliers have been done in verilog code using xilinx ISE 14.7 software and using FPGA Artix7 family 7a100tcsg324-3 device simulated successfully. Modified booth multipliers have consumed 110 to 400 percent more resources than array multiplier. It also consumes 12 to 250 percent more power than array multiplier for different versions. An exponential rise in resource consumption is observed from 8 to 64-bit version of modified booth multipliers while an exponential jump in power is observed for its 64-bit version.
