And not less the "one process" model free You of the demand for a MMU
in the processor, and opens the possibility to use a smaller CPU like
the ARM7 series.

MMU Memory Management Unit, is the hardware that makes separate
address spaces possible, this is not pressent in many small devices,
so here you need an OS that can run without.
