Hi all,

I'm implementing performace tests on an evaluation board with ST10F276 CPU. The goal is to measure cycle performance with some testcases.

How/where can I readout the CPU cycles?

Thank you - Regards,

fvieweg.

Hi,

There is no register providing CPU cycles number.

A simple method to do that consists on measuring the execution time of your application (using timers for example or RTC module) and knowing the CPU frequency you can detemine the CPU cycles number.

I hope I answered your question.

Hi,

thanks for Your answer. I thought about this possibility but hoped for a register.
