# 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](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
