Virtual Memory, Paging, and TLB

Purpose

Explain virtual memory: paging, multi-level page tables, TLB role, page faults, and address translation — bridging OS kernels, embedded MPU, and performance analysis.

When to Use

• Understanding mmap, brk, and demand paging
• Debugging segfaults and guard pages
• Huge pages / TLB pressure tuning
• Contrasting Cortex-M MPU with full MMU systems
