Title: PPC native 68k emulation in AmigaOS3, possible?
Post by: AmigaMance on April 26, 2008, 04:50:28 AM

  Hi.
 I was wondering if it is technically possible to have a PPC native 68k emulator for Amigas with dual CPUs, under AmigaOS3. Something similar to Petunia and Trance which will use WarpOS to run.
 Despite the CPU content switches, do you think that it will be able to execute 68k code faster than a 68040?

I believe OS4 has a 68K emulator in it.

I think that was the whole point of having both CPUs on the Phase5 boards, because they could not figure out a way to emulate the 68k series chips fast enough, so they ended up with the kludge of switching back and forth between the PPC and the 68k CPUs.

OS4 for Classic should give you an idea of how fast the native 68k emulation is, as I believe that it does not use the actual 68k CPU on the CyberStorm & Blizzard cards.
