Abstract
In accordance with exemplary embodiments, a Fast Fourier Transform (FFT) architecture includes elements that perform a radix-2 FFT butterfly in one processor clock cycle at steady state. Some exemplary implementations of the FFT architecture incorporate register and data path elements that relieve memory bandwidth limitations by pairing operands consumed by and results generated by two adjacent butterflies in the overall N-point FFT operation.
