Hi all,

Which function in TI C64xx DSP can return the current system time/
tick? I am measure the processing time of an algorithm, so I need to
get the time before and after the function. I searched the TI
documents, but didn't find any.

And is there any document for the cgtools library?

Normally in embedded systems, I build a timer out of a spare counter-timer peripheral. I include a constant to subtract for overhead, then adjust its value so that the time for an empty routine is zero.
