Detailed Description
Modeling hardware memory management for virtual memory -> physical memory translation and protection.
It is oriented for porting OS to ETISS.
Memory Management Unit is the key component to support OS. Modern architectures vote for TLB to speed up virtual memory address (vma) to physical memory address (pma) translation. Since vma to pma could easily become the bottleneck, it is assumed hardware managed TLB is adopted. As for software managed TLB (old design), MMU has to be modified accordingly.
