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 28 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 28+ Years

For over 28 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.

Reliability

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.

Efficiency

embOS is a high-performance real-time operating system. It has been optimized for minimum memory consumption in both RAM and ROM.

Availability

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.

Fastest time-to-market

First-class support, outstanding documentation and product trainings all serve to define the core of what this RTOS offers. This ultimately serves to reduce time-to-market.

embOS

From battery-powered, single-chip products to high-end systems that demand ultra-high performance: embOS can be used in any application. The embOS RTOS developed by the Embedded Experts is used in a range of different target markets including industrial controls, IoT (Internet of Things), networking, consumer electronics, safety critical devices, automotive to medical devices and avionic. This makes it the market-leading RTOS in the embedded industry.

embOS-MPU

Simplify any certification process by using embOS-MPU to enhance the stability and safety of your embedded applications! The operating system and all tasks deemed privileged are memory-protected and isolated from the negative effects of unprivileged tasks. Thanks to a fully compatible API, existing embOS applications can be adapted to embOS-MPU with minimal effort. SEGGER – The One Stop Shop.

embOS-Safe

Certified by TÜV SÜD, embOS complies with the functional safety standards IEC 61508 SIL 3 and IEC 62304 Class C. This certification highlights the high quality standards of embOS development processes. Ultimately, this makes embOS even easier to use in safety-critical key market segments like medical, automotive, aviation and home appliances. Customers requiring embOS-Safe gain access to a proven, reliable solution with all embOS key features, including multi-tasking, comprehensive communication and synchronization services, along with full memory protection. embOS-Safe is provided with a certification kit containing all necessary documents, including comprehensive embOS safety manual, making it easy to integrate it into your application, even for applications that have not taken advantage of RTOS before.

One Professional Solution for All Applications

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

Products benefit from certified functional safety thanks to embOS-Safe. Certification is in accordance with IEC 61508 SIL 3 and IEC 62304 Class C.

Internet of Things

embOS is designed for ultra low power consumption. It can be used in any battery-powered application.

Networking

embOS is designed for the usage in any networking device. This makes embOS and emNet (TCP/IP stack) the perfect solutions for networking products.

Consumer Electronics

embOS – The first choice of any consumer electronics device. Entertainment, communications or white goods (washing machines, etc.).
