Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M, STM8. It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.

PRTOS is an open-source preemptive real time operating system kernel for embedded applications. It presently supports the AVR and MSP430 architectures. 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

AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. 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.

...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.

Driver module using rtc-driver allowing multiple users to use the real-time-clock. Each task opening the timer device gets its own image of the RTC. Except setting the RTC, all features can be used on a per task basis without frequency restriction.

Rt-Simulator is a library to simulate task behaviors on uni/multi-processors with different scheduling algorithms. It provides a run-time reference by fast-prototyping and it can also used for scheduling algorithm research simulation.

uSmartx is a non-preemptive, multitasking, priority based kernel for use in embedded designs. Its major features are task and time control over system resources, inter task communication and simple memory management.

ftRTOS is a tiny realtime kernel for microcontrollers focused on minimal RAM usage. Fixed priority scheduling, preemptive or cooperative multitasking, no dynamic task and memory management, all objects are defined at compile time.
