💻 Virtual Memory Manager

This project implements a virtual memory manager in C, as part of the exercises presented in Operating System Concepts, Silberschatz, A. et al, 10th edition.

🔍 Description

The virtual memory manager simulates the translation of logical addresses to physical addresses using page tables and TLB (Translation Lookaside Buffer). It supports two page replacement algorithms: FIFO (First-In-First-Out) and LRU (Least Recently Used). The TLB uses FIFO for page translations.

💡 Features

• Virtual memory translation from logical addresses to physical addresses.
• Page replacement algorithms: FIFO and LRU.
• TLB management using FIFO.
• The frames in physical memory are filled from 0 to 127.

Installation

1. Clone the repository:

   git clone https://github.com/Sofia-Saraiva/virtual-memory-manager.git

2. Navigate to the project directory:

   cd virtual-memory-manager/src

3. Compile the code using Makefile:

   make vm

4. Execute the program with command-line arguments:

   ./vm address.txt lru

   Replace address.txt with the path to your input file containing logical addresses, and lru with either fifo or lru to select the page replacement algorithm.

📄 Output

The program will generate an output file named correct.txt containing the translated physical addresses and other statistics, following the provided format for validation.

🛠️ Dependencies

• GCC 13.2.0 or higher
• Linux operating system
