Real-time, modular, microkernel-based operating system under development for i386. The first goal is to support 32-bit DOS protected mode applications made with DJGPP as well as native applications.
Embedded Operating System
EXIRION/OS is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used as a synonym for embedded operating system. EXIRION/OS project, a Open operating system for computers that can be used in specific operations that require execute a task at a time, EXIRION/OS operating system is a monolithic and mono layered task, which can be used to control complex electronic equipment without the use of instruments PLC, offering a wide range of electronic and industrial applications, EXIRION/OS is also an educational tool, it is an open source operating system to use it as an example of building operating systems in universities and technical colleges.
DOS/32 Advanced DOS Extender is a drop-in replacement for the DOS/4GW DOS Extender and compatibles. Being fast, small and flexible DOS/32A can be used in many environments, from embedded systems to DOS emulators, by both developers and end users alike.
Written in pure ASM and Exode with cloud computing in mind.
Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!
FreeMiNT is a free alternative OS kernel for Atari systems & clones
FreeMiNT provides the basis of a free TOS compatible replacement OS that can multitask. Used together with the free system components fVDI (device drivers), XaAES (graphical user interface widgets), and TeraDesk (desktop manager), it provides a modern user interface.
LiteOS is our attempt to write a free OS for calculators known as "TI-68k". TI naturally stands for Texas Instuments while 68k designs the Motorola 68000, in other words the processor running such calculators.
CMAKE build enviroment for LPC2000 and LPC17xx Cortex MCUs
The goal of project is to build CMSIS like environment for LPC2000 series MCU and to write RTOS for LPC2000 and Cortex Microcontrollers
K-OS is an open-source realtime-operating-system based on the OSEK/VDX standard aimed at compiler and microcontroller independence. Currently we support Motorola (Freescale) HC12/HCS12/HCS12X targets.
Simplest kernel for cooperative multithreading
Simplest of possible ways to multithreading on the smallest microcontrollers. This project is demonstration the programming technique of the multithreading with polling the system state. Published code debugged and ready to use in your projects.
ASMIMUX will be a kernel, which includes a Linux ABI clone, to use native Linux programms.
AVR32-FreeRTOS project is dedicated to the port of the FreeRTOS real-time kernel to the Atmel AVR32 32-bit AT32AP700x processor familly . For uc3 version port of the FreeRTOS, please check www.freertos.org !
Andalus is an x86 based OS kernel
A advanced graphical operating system.
Our goal with this OS is to compete against Windows, Linux and Mac OS! We know it's still in early stage. But this fact will not demotivate us! License: Proprietary
This will be an operating system
BirdOS is currently not open source anymore. But we may release Bird DOS open source, right here. Bird DOS should be another OS within the FeatherCode Operating Systems branch. This is for the future though, you can download current BirdOS releases (just not open source) via: https://github.com/FeatherCode/FeatherCode We hope to be more useful on this page, in the future. What happened to v0.10? It's been eaten by an eagle. Seriously though, it was a bad 'operating system' with bad code. We now have rewritten the code. To forget the problems and stupidity with v0.10, which was basically just a text-output OS, we have thrown it away. The project will continue, not open source and completely somewhere else. We're extremely sorry.
Caracal is an IA32 operating system which, once stable, will be used to create tutorials and therefore teach others the basics of writing system software for IA32 processors.
Caracal Boot Loader (cboot) is a second stage boot loader which takes over from GRUB (or other multiboot compatible loader) and prepares the system for your higher-half kernel. It now also includes VESA mode setting support.
Cloudium OS is being written in pure ASM. It's a Cloud-based operating system and designed for simplicity and ease.
Codename Five is an operating system kernel, written as an experiment in learning assembler, written from scratch for x86. It is not (purposely) based on any previous operating system.
Crosos is a SubLinux Distribution
Crosos is a open-source OS. It is based on the Linux Kernel and mostly uses the same code in Ubuntu (but it has been derived from Debian)
Real time embedded multi-thread kernel
This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. In near time is planning create implementations for AVR and STM8.
LSCR is a compilation of helping resources for software development in Assembly language under Linux. It includes system calls reference for kernel 2.6+, FASM include files, example applications, and some utilities.
LusitanOS is a 100% Portuguese effort to build an Operating System based on our own concepts but supporting some things from existing platforms such as POSIX, libc, win32 API, linux/elf and win32/pe.
Micro-80 aims to simulate a Z80 homebrew computer down to the bare metal: 64K RAM, ADM-3A terminal, parallel port, serial port and...3.5" 1.44MB floppy drive?!
MuOS is a Operating System for x86-compatible hardware.
