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,

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

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.

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
