How to calculate the time for running the code in Nios II and Nios V?

Hi,

How do I calculate the time used for executing a command in Nios II and Nios V.

I was using the example in the below link but the results from Nios II and Nios V are different.

https://cplusplus.com/reference/ctime/clock/

-------------------------------------------------------------------------------------------------------

clock_t t;

t = clock();
printf ("Calculating...\n");

... (Anything, or you may put usleep (1000000)

...

...

t = clock() - t;

printf ("It took me %ld clicks (%f seconds).\n",t,((float)t)/1000000);
printf ("It took me %u clicks (%x seconds).\n",t,((float)t)/1000000);

-------------------------------------------------------------------------------------------------------

Nios II

Nios V

Could you share the way to calculate the time taken for running a piece of code in Nios V?

Thanks

    Do you have the compilation result with the code above using Nios II processor?

    Hi @Chris039 ,

    Still in the process of testing. Let me get back to you once getting the testing result.

    Thanks,

    Best Regards,

    Hi @Chris039 ,

    I tested the MAX 10 Nios II Hello World example in Intel FPGA Design Store. I found out for Nios II Interval Timer needs to be added in order to get accurate and valid execution time calculation. Also in BSP Editor, set the sys_clk_timer check image below:

    The execution time of Nios II for running code without looper is 1427 clicks which is close to Nios V execution time of 997 clicks.

    Folder attached below.

    Thanks,

    Best regards,

    Sheng
