TMS320C6747: Partitioned FFT (Convolution)

Part Number:TMS320C6747

Hi,

My customer want to use "Partitioned FFT" on C674x. 
So, about Partitioned FFT, do you have any application note, sample code or library?

I've already checked C674x dsplib. But, there was no this function.
(Even if there is not sample code/guide, I think it can be realized by using fft and ifft functions. Right?)

Best Regards,
Takahiro
