The NVIDIA CUDA Fast Fourier Transform library (cuFFT) provides a
simple interface for computing FFTs up to 10x faster. By using hundreds
of processor cores inside NVIDIA GPUs, cuFFT delivers the
floating‐point performance of a GPU without having to develop your own
custom GPU FFT implementation.
Widely used in applications ranging from
computational physics to
image processing and general signal processing, the Fast Fourier
Transform is an efficient algorithm for computing discrete Fourier
transforms of complex or real‐valued data sets. cuFFT uses algorithms
based on the well-known
Cooley-Tukey and
Bluestein algorithms, so you
can be confident that you’re getting accurate results faster than ever.
