How to get the timing of an API on CPU using Nsight systems

Hi,

I am profiling my code on Jetson AGX Orin, the code contains camera data acquisition and running an image processing algorithm. The camera data acquisition was written as a separate API “getFrame”. I want to get the timing of this API, is it possible using nsight systems. I tried it but I see a large stack that includes the gstreamer internal APIs beneath the getFrame API (I used Gstreamer for capturing from camera).

Is there any way to mute this stack and get the high level timing of the API running on CPU.

Thanks,
MRK

Hi,

There are several filtering options in the Nsight System.
Please check the below document to see if it can meet your requirement.
