Example on how to call FFT in IPP from C#?

[jsrober]

Hi,

Does anyone have an example on how to call the FFT in IPP from a C# application?

Thanks,

John

John, have you looked at the C# IPP sample "csinvoke"? seems to be enough. let us know please if you need specific example, then write which FFT (data type, real or complex ...) you are going to call we can prepare an example for you

Thank you for your reply and your help!

I searched for csinvoke*.* in the IPP41 directory and can't find it. Is it something I download?

I receive real samples at 8k samples per second from a real-time system. I would like to display a power spectrum in my C# application. I assume I want a real->complex FFT. Then I calculate the magnitude of the output of the FFT?

Thanks,

John

I found the IPP samples.

Intel dida fantastic job of wrapping the C functions in C#. I expected to have to do this myself.

I think I can stumble through getting the FFT to work in C#. Of course, if you have a sample, please post/send it. THANKS!

Thanks for your help!
