Virtual Memory - TLB Simulation

Part of ECN 207- Computer Architecture and Organization course

Simulates LRU policy TLB in C++

Detailed problem statement is in question.md

How to run

run test.sh (assuming gcc compiler is installed)

What is TLB?

TLB stands for Translation Lookaside Buffer. It is a cache which is needed for virtual memory.

• stores the recent translations of virtual page numbers to physical page numbers
• used to reduce the time taken to access the physical memory
• if the mapping is not found in TLB, then it is searched in the page table
• it is a small cache, so it is faster than page table

Some abbreviations used in the code

• TLB - Translation Lookaside Buffer
• VPN - Virtual Page Number
• PFN - Physical Frame Number
• LRU - Least Recently Used
