FFT v7.0 Bit accurate C Model - Slow

Hi

 

The function that simulates the FFT seems to run very slow. It takes about 1 second on my PC (Intel Core 2 Duo Windows XP) to do a 4096 point FFT with 16 bit inputs,streaming architecture, even when the process is utilizing 50% cpu time.

 

Is this a reasonable amount that I can expect from this function? Any methods to speed up the processing ? Since my application is FFT intensive, my C simulation runs forever.

 

Thanks
