Hi @Chris039 ,

I have done testing Nios V Hello World Example Design. I'm measuring the time taken for Nios V to run C++ code with looper and usleep(1000000) (code image below) and getting the results (image below):

Time taken: 16771 clicks (0.016771s)

Then I'm measuring the time taken for Nios V to run with only usleep(1000000) without looper (code image below) and getting the results (image below):

Time taken: 994 clicks (0.000994s). Close to your results.

Installed RAM: 16.0 GB

I think the execution time measuring code and your result are both valid.

Thanks,

Best regards,

Sheng
