Abstract
A typical processor central processing unit devotes a considerable amount of processing time in performing arithmetic operations, particularly multiplication operations. Multiplication is one of the basic arithmetic operations and it requires substantially more hardware resources and processing time than addition and subtraction. In fact, 8.72% of all the instruction in typical processing units is multiplication. In this paper, comparative study of different multipliers is done for low power requirement and high speed. The paper gives information of “Urdhva Tiryakbhyam” algorithm of Ancient Indian Vedic Mathematics which is utilized for multiplication to improve the speed, area parameters of multipliers. Vedic Mathematics suggests one more formula for multiplication of large number i.e. “Nikhilam Sutra” which can increase the speed of multiplier by reducing the number of iterations.
