Aim

The aim of the project is to conduct research upon existing operating system kernels based on Assembly, C, and Rust and then implement a minimal bootloader, kernel and a userspace to create a minimal x86 32 bit operating system based on the strengths of the researched kernels and languages.

Objective

• Evaluate existing kernels in Assembly, C, and Rust
• Gather and understand the strengths of each language and determine their capabilities
• Implement a minimal x86 32 bit bootloader, kernel, and userspace based on the strengths of the languages
• Find methods to integrate Assembly, C, and Rust together
• Evaluate the project based on criteria mentioned in the evaluation section
• Display the concepts of OS development and system programming
• Understand proper OS design process and practices
• Explain concepts of memory safety
• Understand the role of Assembly, C, and Rust in OS development and system programming
• Try to explain the modern choices in OS development
