FPGA Implementation of Braun’s Multiplier Using Spartan-3E, Virtex – 4, Virtex-5 and Virtex-6

Abstract

AbstractThe developing an Application Specific Integrated Circuits (ASICs) will cost very high, the circuits should be proved and then it would be optimized before implementation. Multiplication which is the basic building block for several DSP processors, Image processing and many other. The Braun multipliers can easily be implemented using Field Programmable Gate Array (FPGA) devices. This research presented the comparative study of Spartan-3E, Virtex-4, Virtex-5 and Virtex-6 Low Power FPGA devices. The implementation of Braun multipliers and its bypassing techniques is done using Verilog HDL. We are proposing that adder block which we implemented our design (fast addition) and we compared the results of that so that our proposed method is effective when compare to the conventional design. There is the reduction in the resources like delay LUTs, number of slices used. Results are showed and it is verified using the Spartan-3E, Virtex-4 and Virtex-5 devices. The Virtex-5 FPGA has shown the good performance as compared to Spartan-3E and Virtex-4 FPGA devices.KeywordsDigital Signal Processing (DSP)Field Programmable Gate Array (FPGA)fast additionSpartan-3Etruncated multiplierVerilog HDLVirtex-4Virtex-5Virtex - 6 Low power
