about the profiler

When I enabled it, the program execution became very slow, and the profiling result was obtained hardly.

Hello Ed,

When profiling large programs on hardware, this can be the case since the CCS profiler is breakpoint based. Hence it is intrusive and can set many breakpoints (one set for each branch in the program) and all the halts can really slow things down.

What target and emulator are you using?

I would not use the CCS function profiler on C6000 HW targets. The accuracy of the counts can be off. Especially if you have many branches in your functions.
