Memory Management and Paging
Memory Management and Paging
01Key memory concepts
- Virtual memory gives each process a private address space.
- Paging maps virtual pages to physical frames.
- TLB caches recent page-table lookups.
- Page faults occur when required pages are not in RAM.
02Address translation flow
CPU generates virtual address -> MMU checks TLB -> page table lookup (if miss) -> physical frame resolved -> data fetched.
