Performance Comparison of Fast Multipliers Implemented on Variable Precision Floating Point Multiplication Algorithm
The multiplication is the basic arithmetic operation in any typical processor. The multiplication process requires more hardware resources and processing time when compared with addition and subtraction. The accuracy of a multiplication mostly relies on the precision of the multiplication; a variable precision multiplier will have more accuracy than single or double precision multipliers. In this paper, a variable precision floating point multiplier is considered and total architecture for the variable precision multiplier is proposed also four different multipliers are implemented using the variable precision algorithm. The comparative study on performance analysis like delay characteristics and area is done for the considered multipliers.
