- Ray,
-
- That's not too bad a speed! You do have a bit of horsepower, though. :^)
-
- I can get almost realtime for the loop you show in the NON debug version
- of my emulator; about 900k/sec, same instructions. That's on a 25 mhz 68040,
- all caches on.
-
- My code is a great deal simpler than yours, though, and involves no
- function calls to anything, anywhere, other than one call to execute the
- instruction itself. All the non-indexed modes are coded completely inline,
- your example being an immediate mode, it falls in that group.
-
- Emulators are a kick, eh? <grin>
