    Hi , 
    
 
    In the Manual it is described that FFT accelerator implements radix-2 complex floating-point FFT butterfly . 
    
 
    Which FFT function is similar to that of that FFT accelerator.   There are CFFT , CFFTF which will it be .
    
 

    
 
    Thanking you 
    
 
    With best regards and wishes

      Hi Wallman,
      
 
      Apologies for the delay in getting back to you. If you are looking for a way to compare the performance of the FFT accelerator vs the performance of the core, the comparison data is already available in the ADSP-214xx Hardware reference Manual from Pg.No 7-80 . The I believe cfftf library function was used to obtain the performance number of the Core.
