Honored ContributorNIOS-II Cyclone II devboard timer problem
Hi all, my problem is with Cyclone II running NIOS-II. After creating a timer in SOPC builder and implementing it to my design, I am trying to generate periodic interrupts with some desired period...

Honored ContributorGood grief.
The problem is that your CPU simply lacks the time to handle all those spamming interrupts. It needs time to save state, handle the interrupt, and restore state. For reference, a typical system tick clock runs at 100-1000 Hz; running faster than that tends to increase a scheduler's overhead by a great deal. So, just what exactly are you trying to do? Generate a clock out? Pause execution for short periods?
