Run Time Stack Usage

Started by Rachit May 5, 2008
Hello,
I am working on TMS320C54x platform.I am using Code Composer Studio
3.1 to develop application.
How to check run time stack usage on CCS?Is there any other utility
for this?

Thanks,
Rachit Shah

Hi Rachit, There's a very simple technique to do this. In your initialization (before the stack is first used), write some known bit pattern to the entire stack, like 0xDEAD. Then after running your application for some time in a representative or worst-case operating scenario, halt the debugger, examine the stack memory, and see how many 0xDEADs are remaining. -- % Randy Yates % "She has an IQ of 1001, she has a jumpsuit %% Fuquay-Varina, NC % on, and she's also a telephone." %%% 919-577-9882 % %%%% <yates@ieee.org> % 'Yours Truly, 2095', *Time*, ELO http://www.digitalsignallabs.com

Hi Randy, Thanks for guiding me.This is one way to track stack usage. Actually I want to check for stack usage by individual function at run time? Thanks, Rachit Shah

What do you mean by run time.We generally measure the stack size for a worst case scenario. regards Rajesh.D

Hi Rajesh, Rut time means without stop the running application.I want to check stack usage of individual function.There is one sdp470.exe available for Static Stack Depth Profiler. Do you know about this?How to use this on CCS? Thanks, Rachit Shah

If you want to check the stack usage of a individual function just open the compiler generated code for that function and check for the 'link'(in ADI..i dont know wat its called in TI) value.

not the map file, the compiler generated assembly code. in ADI its called .s file i am not sure wat its called in TI.

Hi Rajesh, Thanks, I will check it. What's mean by ADI? Thanks, Rachit
hi rachit,

If you are using CCS then there is a simpler way which might be helpful.
at runtime click the "Kernel/object view" under the DSP/BIOS menu. The
window which opens will give you information about the tasks that are in
your code and their stack usage.
