Title

Implementation of Floating Point Division Using Brent-kung Adder for Area Optimization

Abstract

Floating point division is a core arithmetic widely used in scientific and engineering applications. This paper proposes architecture for double precision floating point division. This architecture is designed for dual-mode functionality, which can either compute on a pair of double precision operands or on two pairs of single precision operands in parallel. The architecture is based on the series expansion multiplicative methodology of mantissa computation. For this, a novel dual mode Radix-4 Modified Booth multiplier is designed, which is used for division in the architecture of dual-mode mantissa computation. Other key components of floating point division flow (such as leading-one-detection, left/right dynamic shifters, rounding, etc.) are also re-designed for the dual-mode operation. The proposed dual-mode architectures Multiplication stage is done with approximate adder circuits which can give better results in terms of Area Compared to standalone Dual mode double precision division architecture. In comparison to prior art on this, the proposed architecture out-performs them in terms of required area, time period. The proposed dual-mode architecture is synthesized Virtex7 FPGA family In Xilinx ISE.
