Cross corr fract and cycles

  
Hi,

I need help in finding  how many clcok cycles does the BF533 need for the 
Cross correlation function--cross_corr_fract16:with n = lag = 16 

I don't have access to any knid of sotware that does it for me...

If anyone has used this function before please let me know the same

thanks a lot in advance
sincerely,
shwetha
