How to get CPU cycles

Mohammed Bey over 5 years ago

Hello,

Could someone point me to a code to calculate the CPU cycles when running a program or a part of it?

I found this code for x86 on this link. I need something similar for ARM.

I am using ARM Cortex-A15 and Cortex-A7.

Best regards.

There is a cycle count register (PMCCNTR) integrated into these processors that you can use: https://developer.arm.com/docs/ddi0438/i/performance-monitor-unit/pmu-register-summary
