Program execution time calculation

binukannur — Wed, 14 Oct 2015 04:06:17 GMT

Hai,

Is it possible to know the program execution time in between two breakpoints in Code warrior?

In my case, there is a bit of code as different functions in ISR. To avoid the overhead of ISR I want to find execution speed of these functions.

Here RTC ISR, and its time is 600ms.

Hello Binu

What is the part number of your target MCU?

Eclipse CodeWarrior v10.x supports the feature for profile, for details, please refer to the help document:

Hai,

The problem solved with Oscilloscope.

I set a GPIO pin on starting point and clear on end .

Measured the time interval between set and clear
