Observing memory performance

I’m interested in observing all interactions with the LPDRAM such as reads/writes/powerdowns etc. The performance counters available seem to only be available for the GPU. Is there a different application that is available or registers I can query that would provide this information? Thanks for any help and information.

Hi kaminsknator,

You may need to develop your introspecter tool to do the measurement, but it’s bit specific, and might not able to show the result well.

You could try to use Tegra Graphics Debugger or Visual Profiler to watch the system performance, then can do the optimization on your developing.

More info can be found from below:


Connect high-end scope or logic analyzer to the LPDRAM bus and monitor it?
It’s not cheap and it’s tricky to do but you’ll be able to see and decode all transactions.
