For over 25 years, embOS has been the preferred RTOS choice for engineers in the embedded market. It offers ease-of-use and guarantees 100% deterministic real-time operation for any embedded device. This real-time operating system is highly portable and fully source-compatible on all platforms, making it easy to port applications to different cores. Tasks can easily be created and safely communicate with each other, using communication mechanisms such as semaphores, mailboxes, and events.
embOS Certification & Royalties
Certified by TÜV SÜD, embOS complies with the functional safety standards: IEC 61508 SIL 3 and IEC 62304 Class C.
The real-time operating system is free for any non-commercial use like education and evaluation, without any technical limitation.
For commercial use SEGGER offers a versatile embOS licensing policy with no royalties at a reasonable price.
embOS is the de facto standard for embedded devices. It is already deployed on several billion devices. The embedded RTOS is also certified for functional safety in accordance with IEC 61508 SIL 3 and IEC 62304 Class C.
embOS is a high-performance real-time operating system. It has been optimized for minimum memory consumption in both RAM and ROM.
Yes, embOS supports virtually any core and compiler. All popular cores and compilers are already supported by more than 80 embOS ports, including over 500 board support packages for the embedded market.
The versatile nature of embOS makes this RTOS a core ingredient of any firmware that has to handle tasks requiring synchronization, timely responses, multiple tasks or threads at the same time. This means it is applied in a wide range of different areas, as seen below. For example, IP stacks and USB-Host side stacks are nearly impossible to run without proper scheduling provided by an RTOS.
Safety Critical Devices
