Hardware Performance Monitor module is available only on e200z7 cores. More info about the Performance Monitor can be found in:

If you have MPC5554 then only some software methods can be used: for example, if some kind of operating system is used, you can measure the time that application spends in idle task. Or you can measure the time needed for execution of some tasks (time base can be used – see application note AN2865 for SW example). Or whatever else – it depends what you need.
