i know well that the 8051 doesn't have mmu...what I need is something as widely available as 8051 but withh mmu. maybe this doesn't exist.
the application is network storage (flash based). I know there are a lot of ic's for this, but i need a soft core.
Well ....There is triscend .... A 8051 fast core with a "kinda" MMU
The triscend E5 has a mapping mecananism that is very close of a MMU
(you have to do the caching yourself)
Otherwise they have also the E7 .. thats an arm with MMU ..
