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.

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics: - Memory and enhanced time partitioning (TSP) - Native support for sporadic, periodic and aperiodic threads - Fixed-priority preemptive scheduler - Execution time protection (threads are prevented from executing for more time than they are configured to) - Small size (full image has ~100 to 300KiB text, ~30KiB data) - Hard real-time determinism - Fast critical sections - Prioritized nested interrupts - inter-partition communication with filters to protect unwanted access - Multicore support (RMP) - Supports ARM9, Cortex-A/R/M and Aarch64, RISC-V64 (64 bits) - The complete TestSuite (see below information) is run successfully for each platform in each release - Tested: more than 170 KLOC of requirement-based tests, executed for each board at each release - Up-to-date User Manual also available See our wiki page for more information.

fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface

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.

FiwixOS 3 is a Fiwix distribution, an operating system made from a software collection that is based upon the Fiwix kernel. It basically comprises a Fiwix kernel, GNU tools, libraries and additional software. All the included software is free and open-source software made available both as compiled binaries and in source code form, which allows modifications to the original software. FiwixOS 3 uses the Newlib v3.1.0 as its C standard library, and the Ext2 as its primary file...

scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.

Unix-like operating system for the TI-89 and TI-92+ graphing calculators.

Free and simply RTOS for AVR at assembler. So far, the AVR Studio is used as a development environment. The system supports the preemptive and cooperative multitasking modes, semaphores. Use a small amount of memory for tasks.

SangMyung Univ. Graduate Project Project: MyRTOS Team name:Software Craftsmanship Description: pxa255 based RTOS. Preemptive Multi-threading,Priority-base,Round-Robin Scheduling, Thread, Semaphore,Message Mail Box,Message Queue Management Support.

A small micro operating system kernel written in C (and partly assembly). Planned features are: software based preemptive multitasking/threading, paging, kernel API, IPC, client/server, security system. The code is designed to be clearly understandable.

XMK is a preemptive multitasking kernel for microcontrollers. Its goal is to provide a RTOS small enough (RAM+ROM) to run on 8bit microcontrollers. XMK provides additional/optional features when scaling up to 16bit and 32bit platforms.

The goal of the Christ-OS project is to create a real time micro kernel operating system with a preemptive kernel for embedded systems.

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
