Software Implementation:

• Modelsim
• Xilinx

Proposed System:

• In this paper present, an efficient implementation of single precision method of floating point multiplier target for Xilinx Vertex 5 FPGA using Verilog HDL. The floating point implementation will cover up with 23-bit exponent, 8-bit mantissa, and 1 sign bit. This proposed architecture implement with high speed parallel prefix adder based Wallace Tree Multiplier. a Wallace tree multiplication will provide effective terms of low logic sizes and more speed of operations. In a recent arithmetic applications based circuit design will have more demand with high speed and low area, in this manner the proposed approach of this work will improve the speed of Wallace tree multiplier using 4:2 compressor method without degrading its area parameter. Thus, the proposed method will integrate more efficient and more reliable Kogge stone parallel prefix, Brent kung parallel prefix, Sklansky parallel prefix addition operation in the Wallace tree multiplication on final addition stage at 16-bit data width. Finally, done this floating point multiplier architecture with Wallace tree architecture included normalized rounding method and to reduce area, delay and power. The error difference will have analyzed using Modelsim Software, and analyses optimized logic size’s, delay and power consumptions.
