Post subject:  DIVU & DIVS accurate timings


This is my first post on this forum.

My purpose is to test my 68000 code on EASy68k in order to have a good idea of its execution time, before running it on real hardware.

In the few tests I ran so far, I have noticed that the DIVU & DIVS always takes a constant number of cycles to execute on SIM68K which seems to correspond to the worst case (longest execution time possible for the operation).

Is there any plan to make these timings more accurate?

I hope my English is no too bad to be understood :wink:
I use EASy68K 3.5 and it looks really good.

There appears to be something wonky about the timings for DIVU & DIVS. I'll take a look when I get a chance.
