Some low-cost processors used in embedded systems do not provide a memory management unit ( MMU ).
12.
VLX supports devices with and without memory management units and can take advantage of hardware virtualization and security support.
13.
Bank switching was later supplanted by 16-bit systems, which in turn gave way to paging memory management units.
14.
It required a memory management unit ( MMU ) to support memory protection, so was not compatible with 8088 processors.
15.
Although SheepShaver does have Ethernet support and CD-quality sound output, it does not emulate the memory management unit.
16.
These caches were implemented with the MC88200 integrated circuit, which contains a memory management unit and an amount of cache.
17.
However, on the 80386, with its paged memory management unit it is possible to protect individual memory pages against writing.
18.
The Ephemeral Garbage Collector only uses physical memory and uses the memory management unit to get information about changed pages in physical memory.
19.
However, the TLB cache is part of the memory management unit ( MMU ) and not directly related to the CPU caches.
20.
However, due to the lack of Memory Management Unit of embedded system, the hardware solution cannot be applied to embedded system.
