A faster FFT in the Mid-West
… into two categories: Library generators (such as FFTW and Spiral) and specialized FFTs (such as prime95). Specialized FFTs have the obvious limitation of being specialized. However they are hand-tuned and generally offer superior performance. Library generators are generic and easier to port. But …

Computing the fast Fourier transform on SIMD microprocessors
… the speed of state of the art libraries such as FFTW (“Fastest Fourier Transform in the West”), SPIRAL and Intel Integrated Performance Primitives (IPP). The conjugate-pair algorithm has advantages in terms of memory bandwidth, and three implementations of this algorithm, which incorporate …

Automatic Optimization of DSP Algorithms
… by highly optimized implementations including FFTW and the WHT package. The results of this comparison show that the SPL compiler produces code that is competitive and, in many cases, faster than the competitors.

Accelerating Embedded HOWFSC Algorithms
… vector vortex coronagraph through the use of the FFTW library, and the acceleration of EFC by implementing adjoint-based EFC in an embedded context. We utilize functional analogs to radiation-hardened processors, using the NXP T1040 in place of the BAE RAD5545, and the NXP LS1046 in place of the …

Nopea Fourier-muunnos – Teoria ja toteutus modernilla C++:lla
… toisiinsa sekä tunnettuun FFT-kirjastoon, FFTW. Lisäksi tutkitaan menetelmien laskentatarkkuutta. Lopuksi analysoidaan vertailumenetelmien tarkkuutta ja pätevyyttä, ja pohditaan toteutuksen puutteita sekä mahdollisia parannuskeinoja. Tutkielmassa esitetään myös FFT-muunnoksesta …

Evaluating FFT Implementations Developed for use on FPGA Hardware
… FFT, the Fastest Fourier Transform in the West (FFTW), has been selected as the benchmark against which the numerical accuracy of the FFT cores under test are compared. Results of this research project indicate that, when tested under the same conditions for default configuration options, the …

Μεθοδολογία ανάπτυξης μεταγλωττιστών με εκμετάλλευση της δομής του λογισμικού και του μοντέλου του υλικού του
… μικρότερο χρόνο εκτέλεσης από τη βιβλιοθήκη του FFTW, η οποία παρέχει ταχύτατο χρόνο εκτέλεσης. Είναι η πρώτη φορά για τον FFT που μια μεθοδολογία λαμβάνει υπόψη τις παραμέτρους της ιεραρχίας μνήμης και του αρχείου καταχωρητών. Μεθοδολογία αύξησης της ταχύτητας του Πολλαπλασιασμού Πίνακα επί …
