Hello and thanks for all the additional infos. Using the /f core NiosII results in my case with the error messages: Megafunction that supports opencore features will stop functioning in 1 hour after device is programmed. Reason: I don't have the correct licens to support the /f core. My network licence supports only the /e core. I also don't know how much does such a licence cost. If the CPU speed is really the "bottle-neck" , I would investigate to buy this licence or alternatively if the licence ist too expensive, I would prefere to install a ARM-7 based Header-Board ( eg. LPC-H21-03/-06/-24 from OLIMEX) on the DE1-Header connector.
