Comparative Study Of Various FFT Algorithm Implementation On FPGA 1

Increased demand and advancements in product design in the field of communication, multimedia, security and safety equipment and other industrial and scientific products have created the need for high volume, low cost, multifunction, DSP based frequency analyzers that can use Fast Fourier Transform ( FFTs)for their signal processing or data manipulation. The paper deals with implementation of FFT algorithms that can compute fourier transform of varied signals in real time for frequency analysis of signals on FPGAs (Spartan-6). With large demand for high dynamic range for applications, floating point implementation is used as fixed point implementation becomes increasingly expensive. The inherent massive parallelism of FPGAs allows these solutions to be competitive to software equivalent
