I tried it on a 1C3-144. First used it on the NIOSII-e and saw a real improvement over the emulated code. But when I ran the code on a NIOSII-f core without the custom instructions it flew, much faster than the -e core and custom instruction (but then the -e core is not that fast. Unfortunately there was not enough space to implement a fast core plus the custom instructions. Bottom line is that if you think you are going to get away with a -e core with hw float then it is still better to use the fast core with emulation. VictorS
