Research ArticleOpen accessIn the keywordsImplementation of Low-Memory Reference FFT on Digital Signal ProcessorYi-Pin Hsu, Shin-Yu LinProblem statement: In order to improve and implement Fast Fourier Transform (FFT), in general, an efficient parallel form in digital signal processor is necessary. The butterfly structure is an important role in FFT, because its symmetry form is suitable for hardware implementation. Although it can perform a symmetric structure, the performance will be reduced under the data-dependent flow characteristic. Even … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,142 accessesView PDFCite
