A fundamental question of longstanding theoretical interest is to prove the lowest exact count of real additions and multiplications required to compute a power-of-two discrete Fourier transform (DFT). For 35 years the split-radix algorithm held the record by requiring just 4n log n - 6n + 8 arithmetic operations on real numbers for a size-n DFT, and was widely believed to be the best possible. Recent work by Van Buskirk et al. demonstrated improvements to the split-radix operation count by…

The Tangent FFT
TLDR
The tangent FFT is presented, a straightforward in-place cache-friendly DFT algorithm having exactly the same operation counts as Van Buskirk's algorithm, and it is pinpoints how the tangentFFT saves time compared to the split-radix FFT.

TLDR
This work shows that an algorithm that computes a length-2/sup n/ discrete Fourier transform using 2/sup 2+1/-2n/Sup 2/+4n-8 nontrivialcomplex multiplications actually provides the attainable lower bound on the number of complex multiplications and provides useful information on the possibility of further improvements of the SRFFT.

TLDR
This article describes another algorithm for computing the Discrete Fourier Transform where the required number of additions and subtractions is the same as in the Cooley-Tukey Algorithm; but therequired number of multiplications is only one half of that in the cooley- Tukey Al algorithm.
