How to measure time required to execute particular part of the code

Ashutosh Pailwan1

I am using CCS v4 version. And the controller I am using is TMS 320F28069 control stick.

I have an algoritim to excute, but problem is that since the algo designed is comptationally intensive, I am interested to measure the time required to excute different sections of the code.

is there any facility in CCS Please guide

Hi Ashutosh,

There's a wonderful feature called "Clock profiler" in CCS that can help you out.

Refer this link for more info: http://processors.wiki.ti.com/index.php/Profile_clock_in_CCS

Hi Ashutosh,

Clock profiler is a great feature no doubt. But personally the best way I feel is to use the GPIO for measuring time. Set a GPIO high before entering the algorithm which you need to profile. Set the same GPIO low after exiting the algorithm. Monitor on oscilloscope.

This is the only method I use. You can see if it works for you.

Yup, I do use both when I've do be damn sure! Else just for an idea (immediate) clock profiler does the trick :)
