Rotator with Feed Forward FFT hardware architecture has been proven for many advance industrial application like bio-medical, Digital signal processing it's more suitable for OFDM aplication,wlan and other application.FFT have vast application but characteristic changes rapidly and then controlled by reducing the area, throughput, complexity of rotator using micro rotator In this method used for synthetization of multi delay path commutator architecture to meet requirement of many DSP applications. Characterization for determination of m-rotator at different angles are cascaded design using rotator. These study help for localization of FFT for different application. The design has the minimal hardware and computational complexity to meet IEEE standards. The coding for m-rotator based FFT architecture has been done using Verilog under XILINX ISE platform. The results are verified and found to be compatible with kintex-7 xc7k70t-3-fbg676.
