Execution Time on Target System

Open Sebastian-G opened this issue 7 years ago • 0 comments

Hi, I'm not so sure how to interpret my Zsim results, so I prefer to ask to make no mistakes.

I would like to know the execution time on the target system, which of these values is the right one? And in which unit is it worth? Is there a Wiki to read about it?

If none of the values is the right one, then I have to go through all cores, edit the required cycles for each one and finally calculate the CPU speed.
