embOS – The Leading RTOS (Real Time Operating System)

embOS is a priority-controlled RTOS (real-time operating system). It is designed to be the foundation for developing embedded applications. This leading RTOS of over 25 years is available for all popular cores, compilers and development tools and has been deployed in several billion devices in a range of application areas.

  • Powerful & easy-to-use API
  • High performance with low memory use
  • Kernel awareness plugins available
  • Zero interrupt latency
  • MISRA-C:2012 compliant
  • Functional Safety Certified with IEC 61508 SIL 3 and IEC 62304 Class C

embOS — The Preferred RTOS for Embedded Systems for 25+ Years

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.
