Profile the C_tutorial project
1) From the menu bar, select Profiler–>Enable Clocks.
The Profile Statistics window shows profile points that are already set up
for each of the four functions, tutor1–4.
2) From the menu bar, select Debug–>Run.
This updates the Profile Statistics and Dis–Assembly window. You can
also click on the Run icon, or F5 key to run the program.
3) Click on the location bar at the top of the Profile Statistics window.
The second profile point in each file (the one with the largest line number) con-
tains the data you need. This is because profile points (already set up for you
at the beginning and end of each function) count from the previous profile
point. Thus, the cycle count data of the function is contained in the second pro-
file point.
