Implementation of Fast Fourier Transform using Resource Reuse Technique on FPGA

Authors(2) :-Praveen Kumar Jhariya, Nitesh Dodkey

The utility of discrete Fourier transform (DFT) plays important role in many of digital processing including linear filtering, correlation analysis and spectrum analysis. In this work we have proposed two FFT designs, design 1 and design 2. In design 1 we have only one butterfly unit and one multiplier and this butterfly unit along with complex multiplier is used multiple times to compute the 8 point FFT. In design 2 four butterfly fly unit and two multipliers which are used 3 times. The number system used in our design is single precision (32 bit) floating point and 8 bit floating point.
