Timing calculations

[MIA]

Hi All,
I m working on DM642 DSP from TI .
I would like to know as to how can i calculate the "time taken by a
particular task/function".
The CCS ver2.21 has the profiler in that,but,it takes hell lot of time(when
using profiler,the CCS goes into Simulator MODE).
Is there any other way around?.
I have tried using DSP/BIOS object STS ,as specified in DSP/BIOS debugging
tutorial.this particular object uses CLKgettime()
function.

Thanks

MA Imran

You could use a 'scope and a spare output if you have one - set it high at
the beginning of the function and low at the end.

You could also use the STS module provided by the DSP-BIOS. This wil
provide time info that can be read trough JTag, for those that dont have
mem scope.
