os-tutorial is an open source educational project by cfenollosa that teaches the basics of building an operating system from scratch. The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and...

This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the...

This is a short simple boot-able program that animates some Lissajous figures. It can only run when the computer contains Bios, and when the computer is booted. The complete source code is here as an .asm file which can be compiled instantly with the Fasmw compiler. It has an interesting way of switching the computer into 64 bit Long mode. It actually switches the computer back and forth between 16 bit and 64 bit mode, easily, with an interesting technique.

Simple 8085 assembler and disassembler for educational use. The 8085asm generates the map file and intel hex file. It support the directives EQU, ORG, DB, DS and END.

JPACS, Java Processor and Cache Simulator, was developed to give a simple and clear tool to simulate a processor with a complete associative memory cache at ISA level, using direct memory access or using a program written in assembly.

A simple CPU simulator whose goal is to make assembly learning easier. This goal is reached giving a simple calculator, called ENIAC, with a simple CPU, called vCPU. The vCPU's instructions are very simple and easy to understand.

TizOz OS is an operating system thought to learn how to develop operating systems. Coded in C its main objective is to reamin simple tough having a lot of capabilities.

Nemesis is a tiny real time operating system kernel based on x86 PCs. Its main purpose is to serve as a simple but realistic example of an real time OS kernel running on real hardware..the purpose of this is that it can be embedded in small devices lik

A simple operating system made for educational purposes. It will be a 32 bit multitasking open source operating system. Latest release covers interrupt handling, device drivers and shell service.

SIMPLE is a computer simulator written in Java. Assembly instructions are written into the virtual memory and the processes during the execution are shown on the screen.

Course Compiler Design I at the ETH Zuerich (Switzerland). The course program is to write a simple compiler for educational language J01 (similar to Java, with restrictions) for a target platform (either DLX, SPARC or x86).
