I would personally try to measure the execution time if it is possible. It's very boring work to try to calculate it, escpecially if you have caches and things like that 

 

You could use a timer to measure the time, do it a couple of thousand time and take a mean value. You could also make a custom instruction to count the number of clock ticks.

Use the timer tick functions to calculate the time. Also, try gprof (gnu profiler).
