complexity of a program in ARM 9E

   Hi all,

   I have been working on AMR-WB,on ARM9E and i am using ADS 1.2 tools.  

 
   Please clarity this doubt.

   1. How to know the complexity of a program?

      I am using profiling method as given in AXD Deguggers Guide (pdf    
   
                                                             document).
 
      a.Select File-> Load the image
        In that dialog,enable the 'profile', flat
        sampling and make the interval as 100 micro.sec.
      b.Select Options->Profiling-> Toggle Profiling
      c.Execute the program
      d.Select Options->Profiling-> Write to file
      e.Save the file(xyz.prf) in that dialog.
 
   But i am unable to open xyz.prf file to see the profiling information?
 
   Is this correct procedure to know the complexity of a program?

   Thanks in advance.
