APPARATUS AND METHODS OF PROVIDING AN EFFICIENT RADIX-R FAST FOURIER TRANSFORM

摘要

In some embodiments, an apparatus can include a memory configured to store data at a plurality of addresses and a generalized radix-r fast Fourier transform (FFT) processor configured to determine a plurality of FFTs for any positive integer Discrete Fourier Transform (DFT) by utilizing three counters to access the data and the coefficient multipliers at each stage of the FFT processor.
