SAM460 owners - ArcEm OCM benchmarking - please help

@Chris

the last ArcEm with tooltype disableocm in the brackets is slower than ArcEm without disableocm in the brackets ! Sometime at start i get black screen and i have to reset my sam and launch again the emulator, the strange thing now is that if i try normal ArcEM and the old ocm, the first one is faster, i'm not able to get the previous results which i posted here. Probably there's something wrong in the implementation of ocm routine.

with new ArcEm_OCM OCM ENABLED:
