Performance evaluation

Hi,

I am developing security solutions for embedded applications on the P2020-RDB design board. I would like to know if there is a way for me to evaluate the overhead of my solution (power, processing, memory) as the target solutions are constrained.

I am using SDK 1.9 Linux image, so any solution being either Linux-based or from a NXP tool/plugin would do. I am using TAP over ethernet for probing, so anything on that direction would do for me too.

Thanks,

Online Power Monitoring
The Lm-sensors tool ( download from http://dl.lm-sensors.org/lm-sensors/releases) will be used to read the power/temperature from on-boards sensors.

Memory and CPU usage, you could use "top" command provided in Linux.

Hi @yipingwang ,

thank you very much for your response. The link seems to be broken.
One question though, aren't these methods intrusive, in the sense that they can interfere with the metrics?

Thanks once again

Please download QorIQ SDK 1.9 user manual from the following link.

Please refer to section "Offline Power Monitoring" section in this user manual.

For the offiline solution, that is great thanks! As for the memory and CPU, top gives me the metrics while they are executing, but I was looking for something that could capture these for programs that execute and end. It is tricky to capture the metrics with top like that.

 

Any suggestions?
