ESP32 Forum

I am in the process of writing some finely tuned modules where performance is critical and I was wondering if anyone is aware of any Performance Analyzers for the ESP32. I'm looking for something like VTune that will analyze my code—either statically or at runtime—and gives me information about cache misses, memory stalls, processor stalls, split loads, etc.

Does such a tool exist for the ESP32 and where could I find it?

Checkout Performance Monitors. Basically, the ESP32 CPUs have performance counters to count/time specific CPU related events (e.g., stalls, exceptions, pipeline bubble cycles etc).

Ah, very cool. Thank you so much.
