Hello,

50 Mhz is the clock speed used by the CPU to process assembler instructions.

Instructions can require multiple clock pulses, this depends also on the cpu type.

​You are looking at a way to slow down the loop:

#include <stdio.h>
#include <unistd.h>
int main()
{
	while (1)
	{
	  printf("Hello from Nios II! \n");
	  usleep(1000000);
	}
  return 0;
}

Best Regards,

Johi.
