    Thread Summary
    
                The user inquired about the FFT function similar to the radix-2 complex floating-point FFT butterfly implemented in the FFT accelerator. The final answer indicates that the cfftf library function was used to obtain the core performance numbers, as detailed in the ADSP-214xx Hardware Reference Manual on page 7-80.

    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
