ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
Tool kit for building highly secure special-purpose operating systems
*** Genode migrated to https://github.com/genodelabs/genode ***
The Genode OS Framework is a tool kit for building highly secure special-purpose operating systems. It scales from embedded systems with as little as 4 MB of memory to highly dynamic general-purpose workloads.
Genode is based on a recursive system structure. Each program runs in a dedicated sandbox and gets granted only those access rights and resources that are needed for its specific purpose. Programs can create and...
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.
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. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.
ELKS is a subset of the Linux kernel that runs on IBM compatible PCs from 8086 up. It is intended to get use out of obsolete old hardware, for use in embedded systems, and as an educational tool.
ELKS has been moved to Github to protest SourceForge's installer adware hijacking. This does not directly affect ELKS, but it does affect many major open source projects such as Gimp and FileZilla by attempting to trick the user into installing adware in order to download these programs. I refuse...
Jari OS is a real-time microkernel operating system which runs in terms of multi-service architecture. Core system consists of its own microkernel μString, core and system services, set of device drivers launched as trusted services.
Roundhouse is a pair of C based embedded software applications to drive model railroad stepper motor based turntables. It consists of a stepper motor code and controller code connected by an I2C network. Written in C for PIC18/PIC16s processors.

The objectives of OCERA is the design and implementation of a library of free software components for the design of embedded real-time systems. These components will be used to create flexible, configurable, robust and portable embedded applications.
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
ROME is a modular, multitasking, embedded operating system. The system is highly modular, with functionality split between multiple processes. ROME provides a zero copy architecture where references to data are passed around.
OpenPalm is aimed at providing a Palm API compatible GUI system for small embedded devices. Not anymore a propritary OS can limit our imagination; not anymore a slow processor can limit our extension. Let's help fulfill these simple requirements.
OOOS stands for Object Oriented Operating System. It's an x86 kernel written in VC++ using domain embedded language techniques. It is not a functional kernel, it's a demonstration of various techniques to use template meta-programming techniques in low-level applications.
beetleOS is a small and flexible real time OS for embedded systems with preemptive multitasking. It also provides a lightweight device-driver framework. It is basically programmed for the ARM7 processor architecture but it could be ported to other archit
