What is chronOS?

chronOS is an operating system scheduling simulator. It is built around two main components:

• A process simulator;
• A memory manager.

It is able to use different algorithms, like FCFS, to schedule processes which are as well simulated. The processes consist of changing an unique integer variable.

The memory manager uses a first-fit algorithm to accommodate new instructions of programs.

How to compile

There are two modes to build:

• debug — outputs very extensive debugging information about the execution of chronOS:

  make debug
  

• release — produces a final version of chronOS with only the absolute essential output:

  make release
  

It is possible to clean the current directories using make clean.

Usage

A file plan.txt with the list of programs and times to execute is expected. Without it the program will not execute.
