Function Profiling on C6747 HW

Florian Wickert

Hello,

I need to profile the function calls of my code but could not find out how to do this.
From what I read so far I have to conclude that this only works with the simulator, which is removed from CCS v6.
The Hardware is EVMC6747 and XDS560v2 JTAG.

Is there any way to measure how often every function is called and how many time/cycles it took?

Thanks!

Hi
I would recommend looking at the Introduction to C6000 Optimization Application note (SPRAFB2).
www.ti.com/lit/an/sprabf2/sprabf2.pdf
There is a code snippet in the appendix section that uses a couple of CPU counter registers, that counts in terms of CPU cycles.

Hope this helps
Regards
Mukul

Hi Florian,

Please refer to the following TI wiki page for clock profiling using CCS IDE.

processors.wiki.ti.com/.../Profile_clock_in_CCS

For profiling , you can use the code snippet mentioned by Mukul.

Hi,
thanks for your reply.
I've already seen the optimization guide, but I have more than 200k lines of code and a large number of functions so implementing cycle counting for each of them is virtually impossible.
Is there any chance to get the simulator running in CCS v6 so I can use profiling as described here processors.wiki.ti.com/.../Profiler ?

The picture next to "Function Profiling Result" shows exactly what I need, but nothing happens when I click the "Activate" button in the "Profile Setup" tab.

Best Regards,
Florian

Hi Florian,
No, in CCSv6, simulator support has been disabled and no more support via forums.
It will be supported only by direct your local TI FAE.
But you can downgrade to CCSv5 and try to use simulator.
Try to install CCSv5.5 and do your profiling with simulator.
