WinUAE needs a 68030 CPU Option

Exodus · 28 April 2004, 04:34

Toni, you have listed all known Amiga Motorola CPUs up to 68040. Perhaps you could include 68030 on the list (I don't see any option). I am redeigning all my UAE confiugurations so far so that the requirements matched the actual Amiga hardware. I'm afraid I can't make an Amiga 3000 config file without the 68030 CPU option.

As far as I know the 030 is just a faster version of the 020 so just up the settings on winuae to take advantage of the superior power of your pc, the 040 has a complete different instructoin set so it needs a separate button, other than that I can't help!

Actually, the 040 instruction set wouldn't be completely different (or older programs wouldn't work), but it does include instructions not found in the earlier CPU versions. I think Toni has indicated before that the 030 really isn't much more than an 020 with an added cache and an MMU, and the MMU isn't currently emulated at all in WinUAE. If the 030 contains any additional instructions not found in the 020, the only benefit you could get from adding the 030 emulation would be if you actually had software that used those added instructions, and I'm not aware of any that does. However if there are any programs like that, then those could be still be used by selecting the 040, since the 040 would include the full 030 instruction set. I might be wrong, but I would think that if you're trying to set up a config to match the A3000's capabilities, then the most accurate CPU to select from the current options would be the 040 because it is capable of everything the 030 is capable of.

Libraries, programs, etc. sometimes come in 68000, 68020, and 68040 versions, but I've never seen a 68030-specific version of anything. This would appear to support the arguments from killergorilla and Chuckles, in that if the 030 is indeed just a faster 020 then there would be no need to compile a separate 030 version. If I'm making any sense!

But until reading this thread, I was wondering about the lack of an 030 option myself. You learn something new every day!
