Simplicity Studio consultation on energy profile related issues [Copy link]

 

When using the AES encryption algorithm for energy harvesting, the built-in energy profile tool collects the energy consumption of the three processes of runtime key expansion + encryption + decryption. What can I do to make it only collect the energy consumption of the encryption process?

In other words, how to write the encryption program into the microcontroller, then put the data to be encrypted into the register, and then let the microcontroller take the data for encryption. . . .

The idea now is to add a trigger signal A before the encryption function is called, and then let the energy profiler tool detect the trigger signal A to start collecting power consumption, and then give a trigger signal B after the encryption is completed, and then stop collecting after contacting the trigger signal B. How should I give this trigger signal? In the energy profiler tool, you can see that there are trigger signal types, including Current, voltage, Power, awake, IRQ, etc. How should I use them?
