  • Forum Post: Re: Exception handling in a multitasking application

    Thanks for the quick reply! Indeed, I did do that. In this test program, there is only one source file, though there are some files (a .c and a .s62 file) generated by the DSP/BIOS. To handle the .c file, I had to specify the -fg option to compile C files as C++, but that doesn't address the assembly...

    An update: It appears to me that the exception handling code is not properly destroying exception objects. (This may be a symptom of a deeper problem, but it may just as well be the problem itself.) Here's what I did. I lock a global mutex in my exception class's constructors and unlock it...

    Georgem Unfortunately, you have wandered into unsupported territory. C++ exception handling uses a data structure, not exposed to the user, to do its job. There is only one copy of this data structure in the system. The different tasks are all modifying this one data structure. Changes made by one task...

    Georgem Well, mlimber, you write some long posts. You ain't seen nothing yet! ;-) WRT "official answer" ... Of course not. It is just a forum post hoping to be helpful. The official answer will arrive in a readme file, or the documentation, or something like that. The way I think about...

    Georgem I have since learned more of the low level details of how exception handling works in the TI compiler. There is persistent state about exceptions that each task presumes is only modified by that task. Putting a mutex around each point where that state is updated is not sufficient. That merely...

    Performing all the exception throws and catches in a single task should (and I emphasize should) work. Build all the non-throwing tasks code without --exceptions. So your answer is that task switching itself is not the problem, which means, contrary to your previous statement, that one can indeed use...

    Georgem I never said whether the task switch itself is the cause the problem. BTW, the task switch itself is not the cause of the problem. At this point, I'm beginning to doubt I'll ever explain this to your satisfaction. It's not that I'm implacable. It's just that I am trying...

    mlimber
    I have an intermittent problem with C++ exception handling when I use multiple tasks ("threads" in normal parlance). The problem is intermittent, but I can reliably reproduce it with the code below. I am using CCS 3.1 with cgtools 5.1.12, and I have enabled exception handling with the -...

  • Forum Post: Why does C6713 run slower than the C31?

    CMA
    Hi, I have to switch to use the new TI DSP chip C6713 because the old C31 is out of production and I can't even find them from surplus stores any more. I'm running the C6713 at 200MHz now, whereas I was running the C31 at just 80MHz before. Nevertheless, I converted my old C31 program...

    Hi! Im developing an audio process for the tms320c6713 and having trouble that whenever I need to do some calculations of the new parameters being used in the realtime process I get an ugly clicking sound. Especially when i'm allocating new memory on the hardware. My question is, can I thread this...
