Abstract

A multiplier plays a vital part in multimedia and digital signal processors. The integer unit alone cannot achieve the desired computational speed required by modern applications. Unit specially designed to carry out operations on floating point numbers is required also commonly known as floating-point unit. The IEEE 754 standard is used for defining the format of floating point number which is widely accepted. Basically, two formats are used for representing the floating point numbers, single precision which works on 32- bit floating point numbers whereas double precision working on 64 bit. Though the number of bits on which double precision operates doubles as compared to single precision number, it is hardly used due to its requirement of very large memory and also the delay generated for the IEEE-754 standard floating point multiplication. This is the mojor reason for its rare implementation in designs requiinge high computing speed.[1] In this paper we are proposing three efficient algorithms for enhancing the speed and optimizing the area required for implementing single precision floating point multiplication. Also compared the results in terms of power dissipation, execution time and area requirement for the implementation with the conventional methods used. Here the algorithms are implemented and analyzed by using the most popular semi-custom design tool Vivado ISE 2015 and is synthesized by using Artix-7 FPGA and the same is reflected in the mathematical model purposed for each circuit.
