FFT (Fast Fourier Transform) is a technique by which one can perform 1D and 2D transforms on discrete data. Typically Discrete Fourier Transform is the primary application of FFT. One implementation of FFT is available at www.fftw.org. FFTW is currently available for multiple platforms including Windows and Linux.

I was looking for a framework to run FFT operation on a Windows Mobile 6 platform in native C++. Unfortunately, there are none. So, I decided to port the framework myself and indeed I was successful too. I have placed the framework at www.sudarsun.in/downloads/FFTW-3.0.1-ARMV4I.zip. It does not contain any documentation. I shall update it ASAP.
