Intermediate Topic 29 of 51 Computer Architecture & Logic

Virtual Memory in Hardware

Address translation giving each process a private space.

How it works

The MMU translates virtual addresses to physical ones with page tables, giving each process an isolated address space and permitting memory larger than RAM via swapping.

Where it is used

Process isolation and memory protection.

Common pitfall

Page-table walks are slow without a TLB.

Where it fits in the course

Virtual Memory in Hardware is topic 29 of 51 in Computer Architecture & Logic, rated Intermediate. It follows Cache Replacement Policies. The next topic is TLB.
