How do I calculate time for certain functions in MPC5777C?

I am using s32ds power architecture 2.1 and I am currently trying to calculate encryption/decryption time for cse project.

I tried using time.h but I don't think it works in s32ds.

Is there any way I can do?

Hello,

You can use for example external tool like Trace device to see the execution of instructions.

Or you use performance monitor located on core:

Please refer to the Chapter 8 Performance Monitor of core reference manual.

Best regards,

Peter

Is the manual for MPC5777C? because I don't think I have the same reference manual as yours. Mine says System Integration Unit for chapter 8

Hello,

I was referring to core reference manual, not uC reference manual.

Best regards,
