TMS320C6678: In-Place FFT functions optimzed for c6678

Part Number: TMS320C6678
Other Parts Discussed in Thread: FFTLIB

Hi,

I am trying to use TI's DSP_lib fft functions for my project (I want to comptue ffts of size 64 up to 16384). Unfortunately, I realized that none of them is in-place capable and I do not have enough storage  to "waste" on an fft output array since I immediatly need the result back in my input array.

So here is my question:

Is there any other FFT implementation despite the DSPlib one which is in-place capable and optimized for c6678?

Currently I am using DSPF_sp_fftSPxSP_r2c(...) and DSPF_sp_fftSPxSP(...)

Thanks

Paul
