Other Parts Discussed in Thread: SYSBIOS

i 'm working on 6678EVM on sysbios environment.

i'm treying out the mutex example (with modifications to run my functions).

how can i time the fucntions. i want to know how much time is taken for execution of the function.

i'm using a priority 1 and priority 2 task, blocking the critical section with a semaphore, i want to time the critical section.

Hi Pratheek Suresh

You can read the core register TSCL and TSCH before and after the function you want to know it's exectution time.

Here's a good thread on Timing/Profiling. http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/130875.aspx#469012 It should cover all your questions.

Best Regards,

There's a reference link in the thread I referenced going to the processors wiki page that has good examples.
