WebFFT DSL is FFTW [5], which is the most widely used open-source FFT library. At its heart, FFTW is an FFT compiler, based on Objective Caml, to generate Directed Acyclic Graphs (DAG) of FFT algorithms and performs algebraic optimization on them. FFTW uses a planner at runtime to recursively decompose the DFT problem into sub-problems. These … WebIt includes complex, real, symmetric, and parallel transforms, and can handle arbitrary array sizes efficiently. FFTW is typically faster than other publically-available FFT implementations, and is even competitive with vendor-tuned libraries. (See our web page for extensive benchmarks.) To achieve this performance, FFTW uses novel code ...
