FreeRTOS, which was developed in partnership with some of the world's most renowned chip companies over a 15 year period, is now downloaded every 170 second. It is a market-leading real time operating system (RTOS), for microcontrollers, small microprocessors. FreeRTOS is freely distributed under the MIT open-source license. It includes a kernel as well as a growing number of IoT libraries that can be used across all industries. FreeRTOS is designed with reliability and ease-of-use in mind. The FreeRTOS kernel has been trusted by leading companies around the world as the standard for microcontrollers/small microprocessors. It is known for its reliability, small footprint, and wide device support. You don't need to know how to set up a project. There are pre-configured demos that can be used as templates and IoT reference integrations. You can quickly download, compile, then get to market quicker. Our partner ecosystem offers a variety of options, including professional support and community contributions.

embOS (real-time operating systems) is a priority-controlled, RTOS (real time operating system). It was designed to be the foundation of embedded applications and has been continuously developed since 1992. Since 1992, embOS is the preferred RTOS for embedded market engineers. It is easy-to-use and guarantees 100% deterministic, real-time operation on any embedded device. This real-time operating platform is portable and fully compatible with all platforms. It also allows for easy portability to other cores. You can create tasks and communicate with others easily using communication mechanisms like semaphores and mailboxes. The real-time operating system can be used for non-commercial purposes such as education and evaluation without any technical limitations.

LynxOS is used in millions of embedded devices. It has been reliable for over 30 years in multiple safety- and security-critical embedded markets. It is a proven method for hosting applications on Unix-like OS models. All resources and application services are centrally managed and controlled by a single kernel. This is ideal for working with older hardware architectures. We want our customers only to purchase what they require. While real-time operating systems can be a great asset to embedded system designs, they are not necessary. Our RTOS-related resources are listed in our Embedded Systems Learning Center. This center contains helpful information to help you make software purchases as you design, update, and maintain your system. It also provides information on which real-time platform vendor is best for you.

QNX's real time operating systems have been used by thousands of companies since 1980 to provide the best combination of security, performance, and reliability in mission critical systems. The core of QNX technology lies in the QNX Neutrino® Real-time Opera System (RTOS), which is a fully-featured RTOS that enables next-generation products in all industries where reliability is important, such as automotive, medical devices and transportation. A component failure does not affect the kernel or other components of the QNX microkernel architecture. The system can be shut down and restarted with no adverse effects from the failed component. The QNX Neutrino RTOS provides the determinism that only a real-time operating system can offer. Techniques like adaptive partitioning ensure critical processes get the cycles they require to complete their tasks on schedule while still maintaining the performance required by complex embedded systems.

Deos™, DDC–I's safety-critical space partitioned real time operating system (RTOS), has been tested to the guidance DO-178C/ED-12C Design Assurance level A (DAL-A) for Avionics Applications. It supports ARINC 653, APEX, and rate monotonic scheduling (RMS) and is targeted at FACE Safety Base Profile. Since 1998's audit by Transport Canada, it has been field-proven as a safety-critical RTOS. It has been certified and is currently flying in tens of thousands of aircraft. It has evolved over the past two decades with new processors or features in subsequent baselines. It has been audited successfully by various governmental certification agencies (FAA, ENAC and JAA, EASA and EASA), and airframe and Avionics Supplier Designated Engineering Representatives.
