Low Power High Speed 16x16 bit Multiplier using Vedic Mathematics

High-speed parallel multipliers are one of the keys in RISCs (Reduced Instruction Set Computers), DSPs (Digital Signal Processors), and graphics accelerators and so on. Array multiplier, Booth Multiplier and Wallace Tree multipliers are some of the standard approaches used in implementation of binary multiplier which are suitable for VLSI implementation. A simple digital multiplier (henceforth referred to as Vedic Multiplier in short VM) architecture based on the Urdhva Tiryakbhyam (Vertically and Cross wise) Sutra of Vedic Mathematics is presented. An improved technique for low power and high speed multiplier of two binary numbers (16 bit each) is developed. An algorithm is proposed and implemented on 16nm CMOS technology. The designed 16x16 bit multiplier dissipates a power of 0.17 mW. The propagation delay time of the proposed architecture is 27.15ns. These results are many improvements over power dissipations and delays reported in literature for Vedic and Booth Multiplier.
