A HIGH SPEED BINARY FLOATING POINT MULTIPLIER FOR ALL PRECISIONS

M. Deepika, D. Jhansi

Abstract


This paper presents upto double precision floating point multiplier [8,16,32,64] in verilog.  In addition, the proposed designs are compliant with IEEE-754 format and handles over flow, under flow, rounding and various exception conditions.  A high speed floating point double precision multiplier is implemented on FPGA.  The developed multiplier is implemented using Verilog HDL for the target FPGA Virtex-6. The designs are verified using Xilinx ISIM simulator.
