...It is intended for smaller microprocessors, such as the AVR, MSP430, PIC24 and Cortex M0+, and smaller systems of maybe a dozen tasks. CoRTOS is not a task scheduler. CoRTOS works like any other RTOS. Tasks schedule themselves, picking up where they left off after making a call to the OS. The intended audience includes: • Those needing a small footprint RTOS; • Students learning about real time systems; • Makers wanting to program "close to the metal." CoRTOS is released by Cleveland Engineering Design, LLC - developer of PRTOS pre-emptive RTOS https://sourceforge.net/projects/prtos-preemptive-rtos/ and the CTREE analysis tool https://sourceforge.net/projects/ctree-graphic-tree-generator/

...The advantages of PRTOS are: It has the smallest footprint of any true preemptive system: 1.9kB for basic scheduling and task control, 5.1kB with all the features below (AVR '328 / gcc -Os); Only 950 lines of code implement all of the RTOS features (SLOC-L); The system is well documented with a comprehensive manual, well-commented source code, and a test suite demonstrating the features; The system is proven - it has been in use since 1982 with applications in in-vitro medical equipment, process control instrumentation and industrial machinery; PRTOS is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative RTOS https://sourceforge.net/projects/cortos-simple/ and the CTREE analysis tool https://sourceforge.net/projects/ctree-graphic-tree-generator/ Commercial licensing is available

OS9exec - execution environment for OS-9/68k user-mode programs on MacOS9 / MacOSX / Windows and Linux host OS. (OS-9 is an RTOS of Microware/Radisys)

...flAVR also implements the GDB remote protocol, allowing it to interface with Eclipse and other IDEs supporting GDB. The simulator also supports kernel-aware co-simulation when running binaries linked with the Mark3 RTOS, providing it with virtual input and graphics devices. The project is designed to be highly-portable, and builds with minimal dependencies. Currently, flAVR builds have are targeted to Windows (MinGW) and Linux (GCC).

Nano OS is a RTOS for Atmel AVR controllers. It provides: -preemptive realtime multitasking incl. priorities, -binary semaphores, -message queues, -array-based memory management , -functions for taskcontrol, -watchdog, -system management functions

...It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.

...Includes the FunkOS Realtime Operating System by Funkenstein Software Consulting, available at http://funkos.sourceforge.net Mainly it is a support package for the development board Perseus, but I have ported also the RTOS to MCF52233DEMO board. More to come....

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.

mango is a free, open source, lightweight HTTP Client library written entirely in C. The focus of the mango implementation is to reduce resource usage while still providing an almost full-scale HTTP Client. This makes it suitable for use in memory-constrained embedded devices where memory and CPU power are at a premium.

Akalon is a Bare-Bones Embedded RTOS that's designed to be simple and portable to any Microprocessor or System (Board). Currently supports the Intel and ARM Architectures.

CortOS is an Embedded RTOS 1. It is a free and open 2. Task switch is very fast 3. Interrupt service routine uses a separate stack 4. Calculate running time of Task 5. It is a real-time multitask kernel which accords with CMSIS ( Cortex Microcontroller Software Interface Standard ). 5. <Atmega328> <ARM Cortex-M3> <ARM Cortex-M4 with FPU> <STM8>

Run GPOS and RTOS simultaneously on multi-processor platforms.

The project proposes to develop Ethernet interface for an AC drive using MCF51CN128 microcontroller, MQX RTOS and JavaScript and hence make remote control of AC drive feasible through Ethernet and further via internet, to control an AC drive

pico]OS is a highly configurable and very fast real time operating system (RTOS). It targets a wide range of architectures, from very small 8 bit processors and microcontrollers up to very huge platforms. Ports are available for ARM, AVR, PPC, MSP430, 6502, MYCPU and for developing and testing purpose also for 8086, Win32 and Unix. pico]OS 1.0.4 was released 2012-07-12. This is a maintenance release that includes some bug fixes for the new ports for MSP430 and ARM Cortex-M. ...

CooCox CoOS is a free and open-source embedded real-time multi-task OS specially for ARM Cortex M series.

NCOS is a simple RTOS derived from uC/OS-II. Surpport 32-bit MCUs, such as STM32, LPC2000, etc.

this project is dedicated to muticore chip.

This is an RTOS for the PIC24xxxx from Microchip. It is somewhat catered to the PIC24. I wrote a little demo app to go along with it. Enjoy for now!

A Small, Reliable, Compact, Object-Oriented, Portable RTOS(Real-time operating system).

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.

Course project for MTE241.

FunkOS is an RTOS for 8-32 bit MCUs including AVR, MSP430, and Cortex M3. Both C and C++ kernels avaiable. Key features include preemption, periodic events, device drivers, and mutex/semaphores. Includes a variety of graphics and filesystem middleware. Please also check out FunkOS's big brother, Mark3OS. Mark3OS is slightly larger, but is more scalable, much more feature-rich, and supports a wider variety of devices.

Ivmuk-OS is small RTOS for microcontrollers with low resources. Microchip's PIC16F877A MCU uses about 70 bytes of RAM and 800 bytes Flash. Memory usage depends on number of tasks and messages defined. This should create competition to Salvo OS some day.

'EOS' is a fully-featured preemptive real time kernel developed for the Infineon XC167 microcontroller. Performance summary: A typical context switch will take about 100[microsecond] at 40[MHz], when all tasks have a stack of 256 bytes.
