FFT Fast Fourier transform in Verilog xilinx using butterfly net radix 2 by tss40

I want a Butterfly network in the multi core project I will give you ,written in Verilog Xilinx, to execute 1D-FFT with BN-FFT algorithm. that FFT uses complex real numbers it means I want floating-point/fix-point… (Budget: $30-$250 USD, Jobs: Verilog / VHDL)
