Title: ColdFire gets MMU
Post by: Dan on May 17, 2004, 10:08:07 PM

Freescale has expanded it´s Coldfire cpu-family with two new chips with MMU.  Could be interesting for the AmigaColdfire project.

It's highly unlikely the MMU is compatible with the M68K one, so I fail to see how this would help AmigaColdfire. Supervisor level is totally different in other parts already, so if supervisor support is needed, it will require full interprative cpu emulation.

MMU is not useful in emulation itself either, direct "traps" in emulation opcode range are faster anyway.

Ah, but if we could get a coldfire nativly compiled version of OS4 then that MMU might come in to play. Wishfull thinking perhaps.

AROS seems more realistic than OS4.
Does AROS use MMU?
