How can I check the current usage of ethos-u65 NPU on imx93-evk?

[dpcivl]

Hi, I'm doing some test with my imx93-evk board.

By the way, I have a problem with checking how many resources the NPU on imx93-evk is using.

I want to know the proportion of NPU usage when I execute the program which is about object detection.

I referenced "iMX Machine Learning Guide" but I couldn't find what I want to know.

And I didn't understand how to profile NPU usage when I work with tensorflow lite and python(not benchmark_model).

+) I used /sys/kernel/debug/gc to see usage of NPU/GPU when I worked with imx8mplus-evk board.

Anyway, I want to find the way I can check NPU usage(%) in doing object detection.

Thank you.

Hello. Are there any updates on this topic? I'm also wondering how to check NPU utilization (%).

Hello @dpcivl 

Please refer here:

https://docs.nxp.com/bundle/AN13917/page/topics/use_cases_and_measurement_results.html

In section i.MX93 processor power measurement.

Best regards.

Not for power measurement. During executing my program, I want to know how many NPU resources my program uses out of 100 percent. I just want to optimize my program to reduce load for NPU and I need to see the load of my program for NPU.
