ARM OS Project on IntegratorCP / ARM926EJ-S

Overview

This repository implements a simple operating system kernel and supporting components for the ARM926EJ-S processor, running on the IntegratorCP board (or equivalent emulated via QEMU).
The project is developed as part of a Computer Engineering course at the University of Florida.

Repository Structure

• common/ — Common utilities, constants, and architecture-specific definitions
• include/ — Header files for the kernel, user code, and system interfaces
• kernel/ — Core kernel source code: initialization, scheduling (if any), system calls, and interrupt handling
• home/ — Optional directory for user applications or sample code
• scripts/ — Build scripts, toolchain invocation, and QEMU launch scripts
• user/ — User-mode programs that run on top of the kernel
• .gitignore — Standard ignores for build artifacts and temporary files

Features

• Bootloader and early system initialization for ARM926EJ-S
• Exception and interrupt vector setup
• Basic memory management (if implemented)
• Kernel and user-mode separation with syscalls and traps
• Simple user-mode program execution
• Emulation support using QEMU
