Hello everybody,
I'm new to Parallella board and embedded programming in general, I hope I'm not asking a trivial question.
I'm porting a program on the board to evaluate its performance. It uses the __clock64() from OpenCL function to obtain a timestamp and I'd need something equivalent.
Is there anything in the Parallella SDK?
Thanks in advance

I don't know about the OpenCL environment, but if you use the Epiphany SDK and plain C, you have access to the Timer/Counter blocks of the Epiphany. These allow you to count clock cycles (among other things), but are not well-suited for timestamps, since the counters stop at zero. Check the SDK documentation for the e_ctimer_* functions.

Thanks for your tip, I'll look better the docs to understand if it fits my case.
