The M3 would at best have MPU rather than a full MMU. Most full operating systems on x86/Cortex-A prefer the MMU for performance and security reasons. However real time operating systems use tasks/threads over processes, most of the time without even MPU.
Cortex-M is pretty small to have a full MMU. M3 generally sticks to full speed due to the RAM size. Now they could fix this in AXI without question, but I would recommend M7 for that. (512MB of DDR3 on 8-bit would be possible.) This would required a custom OS more than likely.
