How can i calculate function execution time in IAR

[SumitS]

Hi,

I want to know what is my execution time for each function. I am using nrf51822 chip and the IDE is IAR Embedded Workbench. How can i calculate the execution time of each function

I don't know if IAR has a special function to that, but some generic solutions are:

• Toggle a GPIO pin right before and after calling the function then use a logic analyzer to measure the time.

• User a timer, capture the timer counter value before and after the execution.

I've seen few articles from IAR. Haven't tried myself, prefer GPIO. link1 link2 link3
