CCS: C5505 FUNCTION EXECUTION DURATION

Hi Ki-Soo,

your tip is very helpful!

One thing: where can i find a detailed description of clock functions API?

Thanks a lot

Kind regards,

Paolo

Are you asking about the DSS APIs for the profile clock?

Yes, thanks Ki-Soo

The API documentation for the profile clock can be found in:
<CCS INSTALL DIR>/ccsv[x]/ccs_base/scripting/docs/DS_API/com/ti/debug/engine/scripting/ProfileClock.html

Thanks

Hi Ki-Soo,

in order to measure the time duration of my function i proceeded in this way, that, if it is correct, seems to be simple:

- clock (in cpu cycles) enabled and shown.

- I put a break point in Debug mode before calling my function. When the execution break i annotate the clock cycles elapsed before calling the function

- I make a step over and reannotate the new clock cycles after calling the function.

- I make the difference (cycles_diff) : this should be the number of clock cycles 'consumed' by the functions

- I convert the clock cycles in seconds by making the proportional equality (cpu clock PLL 120 Mhz): 120,000,000 : 1 sec = cycles_diff : time_elapsed. This implies:

time_elapsed =  (cycles_diff / 120,000,000) seconds.

In your opinion, in this correct?

Thank you so much

Paolo

Thanks a lot Ki!

Paolo
