FFT in IPP only takes dimension as power of 2?

[missing__zlw]

Is this true? If so, why? It is not very convenient for only have FFT with dimension as power of 2.

MKL supports other dimensions numbers.

Hi,

You are right, IPP supports transform size is power of 2 only. Refer to IPP and MKL Choosing a High Performance FFT.

Thanks,

Hello,

you should be able to use IPP DFT functions. They do support non power of 2 length.
