Embedded Operating System Code

This repository contains the final embedded operating system code I developed for my Operating Systems class at Marquette University.

During the course, we encountered an "unsolvable" issue with the RISC-V framework provided by my professor after implementing memory protection. As a result, we had to migrate to the MIPS architecture for subsequent feature implementations. Due to this transition, I have included two incomplete versions of my operating system:

RISC-V Implementation

This folder contains my work on the following components:

• Serial driver
• Context switch
• Trap handlers
• Process scheduler
• Memory protection

MIPS Implementation

This folder includes my work on:

• File system
• Authentication layer
