CCS/TDA4VM: Who do I profile C7x applications?

Tool/software: Code Composer Studio

Hi TI team,

I was wondering how I can profile C7x application? What is currently possible and how do I trigger profiling in CCS? I see options to create a profile for data collection, but I don't get it to work. Could you also give an overview of what measures can be profiled for C7x applications, i.e. memory access efficiency, memory - computation balance, etc... I worked a lot with the NVIDIA profiler for GPU applications and this offers a lot of insight. I know the the C7x is new and of course I don't expect a similar feature set, but a road map for what is planned would be interesting.

Thanks for any information.

Kind regards,

Florian

    Hi Florian,

    as a starter you can check sections "3.3.6 Symbolic Debugging and Profiling Options", "3.14 Enabling Entry Hook and Exit Hook Functions" , "4.12 Debugging and Profiling Optimized Code" in "C7000 Optimizing C/C++ Compiler":

    I will check with C7xx experts for more appropriate options and will get back to you soon.

    Regards,

    Hi Florian,

    In addition to what Yordan has mentioned, CCS has two options available:

    1]  a profile counter (Run->Clock->Setup/Enable).  The count value will be available in the status toolbar at the bottom of the debugger window

    2]  a "Count Event" operation exposed in the Breakpoints window (View->Breakpoints).  In the case of the Breakpoints Window, the "Count Event" operation can be added by:

    a] right clicking in an empty cell and selecting Breakpoints->Count Event
    b] right clicking on added Count Event and selecting "Breakpoint Properties"
    c] Choosing the appropriate event category via "Event Categories"
    d] Selecting one or more events that you wish to contribute to a counter
    e] Clicking "Apply and Close"

    The counter value will be presented under the "Count" column of the Breakpoint Window

    regards,
