🔵 SEGGER embOS RTOS family

High-performance real-time operating systems

embOS RTOS

  • Deterministic real-time behavior for precise control
  • Optimized for efficiency and low resource consumption
  • Certified RTOS variants for safety-critical applications

Key features

embOS is built to empower developers with the tools they need to create efficient, reliable, and scalable embedded systems. Its design reflects decades of refinement, ensuring it meets the diverse requirements of modern applications while remaining adaptable to a broad range of hardware and development environments.

Reliability

Now in its fourth decade, embOS has proven its reliability after being deployed in several billion devices. An edition certified for functional safety in
accordance with IEC 61508 SIL 3, IEC 62304 Class C, and ISO 26262 ASIL D is available as well.

Efficiency

embOS is a high-performance real-time operating system. It is a true lightweight RTOS optimized for minimum memory consumption in both RAM and ROM, as well as for high speed and versatility.

Availability

embOS supports virtually any core and compiler, offering more than 100 ports and over 500 board support packages for the embedded market. It integrates seamlessly with all major compilers and embedded development tools, including SEGGER's
Embedded Studio.

Use cases

embOS is suitable for a wide range of use cases across a variety of embedded applications. In general, something
that all use cases have in common is that they involve one or multiple microcontrollers or processors.

Battery powered devices

Wherever power is a valuable resource (such as with handheld devices), low-power operation modes should be employed as often as possible. All embOS RTOS editions include features (like tickless RTOS support) to significantly reduce power consumption, and they are tailored to run on even the smallest microcontrollers.

Networking and IoT

Connected networks introduce a variety of tasks
that might interfere with the original intended use
of the device. All embOS editions provide robust
and proven RTOS scheduling and task
management functions to ensure safe operation
under adverse conditions. This makes embOS an
ideal loT RTOS.

Safety-critical devices

embOS-Safe's functional safety certification is in
accordance with IEC 61508 SIL 3, IEC 62304 Class C, and ISO 26262 ASIL D. Certification is achieved without modifications to the backbone, which serves as a foundation for all embOS editions.

Precise and predictable control systems

Closed-loop and other control systems require
real-time conditions to operate. embOS warrants
deterministic behavior by design, minimizing or
even removing RTOS latency and jitter. embOS-
Ultra takes precision even further by providing
enough headroom for future applications.

embOS editions

embOS-Ultra

The next generation RTOS
embOS-Ultra offers higher
precision and time resolution than any other RTOS on the market,
creating the best RTOS for
deterministic applications. This also results in less energy consumption and improved erformance.
