Basic Cycle-Counting ,dose it work?

I want to measure cycle time in bf706  using CCES,according to the >DSP Run-Time Library  >Measuring Cycle Counts>Basic Cycle-Counting

here is my code,

cycle_t start_count;
cycle_t final_count;
START_CYCLE_COUNT(start_count);
for(i=0;i<1000;i++)
{
temp[i]=i;
ans=ans+temp[i];
}
STOP_CYCLE_COUNT(final_count,start_count);
PRINT_CYCLES("Number of cycles: ",final_count);

but , it don't have any output , 

What method should I use to see the output :cycle time?

thanks!
