First In First Out Page Replacement Algorithm - FIFO

This is an implementation of the First In First Out (FIFO) page replacement algorithm.

Overview

This is a C program that implements the First In First Out (FIFO) page replacement algorithm. The program reads a file containing a list of memory references, and simulates how the memory management system would operate with a given number of physical pages and page size.

Usage

The program calculates the number of page faults for a sequence of memory references (i.e., the memory reference trace in the .mem-files) when using the FIFO (First-In-First-Out) page replacement policy.

The program takes the number of physical pages, the page size, and the name of the trace file:

./fifo no_phys_pages page_size filename

The program then returns the resulting number of page faults for that specific combination of number of pages and page size, for either mp3d.mem or mult.mem. Example execution:

 ./fifo 4 256 mp3d.mem

Output:

No physical pages = 4, page size = 256
Reading memory trace from mp3d.mem... Read 100000 memory references
Result: 11940 page faults
