The column on the right, "Pages", contain links to detailed information on rocFFT
rocFFT library includes the following Fourier transformation features
- 1D, 2D & 3D
- power of 2, 3, 5 and mix of them, from size 1 to 2^27.
That is, the input sizes that can be written in the form
2^a × 3^b × 5^c
. The smaller the prime factor, the better the performance, i.e., powers of two are fastest. - Single and double precision
- Complex transforms
- Real transforms (internally uses complex)
- In-place and out-of-place transforms
- Interleaved layout, planar layout is not supported currently
- Unit (=1) stride (packed) for 2D and/or 3D. Unit and Non-unit stride (non-packed data) for 1D
