The thing that i do not understand is: The Coldfire is (Mips wise) roughly 4 times faster than a 68060 @ 70 MHz it shares a good lot of instructions/adressing modes with the 68k (75%?). Why shouldn't it reach the performance of an 68060 or more?
I explained this 4 years ago in June 2003 already. See
ColdFire V4 Amiga accelerator project from the m68k emulation perspective.
Anyhow, my prediction for the resulting speed wasn't far off. Dragon is actually slower than my predictions for the practical coldfire accelerators.
