Measurement individual core usage on TC39xx

[User18983]

Hello all,

I am wondering that is there any way to measure/capture individual core usage on uC TC39xx.
One approach I found is calculate the percentage of time the CPU is not in idlle time ( OS awareness is required).

Target device : TC397x.
Debugger : Lauterbach PowerDebug USB with Trace32 PowerView.

Thank you in advance!

Regards,
Cuong

Hi Cuong. Each CPU core has performance counters that can be started or stopped at user-definable addresses. The counters measure clocks elapsed, instructions executed, and a few selectable counters (cache misses, cache hits, etc.). Refer to the Core Debug Controller in the TriCore Architecture Manual for details.
