Re: Embedded linux: With or without MMU

(Besides the potential difference in hardware execution speed) With any task switch the OS has to do some work to reprogram the MMU (and with ARM the cache gets invalidated).

Are you sure about this ? If it were true, the performance would completely suck. Remember, ARM was originally designed for desktop use as well, AFAIK .. wasn't it used in those Acorn Archimedes machines ?

There are two ways to handle cache and MMU - you can cache by physical address (which causes slower access to the cached data, as addresses need to be translated before accessing the cache), or you can cache by virtual address. ...
