EVM Omap L137 processor time

Tobias Brack
Prodigy 160 points

Hello,

I'm using the EVM Omap l137 for a little control task.
I worry that the processor is too slow to make all calculations in the appropriate time range, which is in my case 1/48000 s.

So is there a possibility to measure the time my algorithm needs to run through? Or any other possibility to find out potential errors of the type mentioned above? 

Best regards

Tobias

    Tobias,

    Is the code running on ARM or the DSP. Have you used compiler optimization while compiling code? Are all levels of cache enabled? Can you run the time critical code from internal memory?

    You can use TSCL and TSCH counters built in on DSP or clock modules in the BIOS/ Linux to benchmark your code.

    Regards,
