Overview
embOS-Base is a preemptive RTOS designed to be the foundation for developing embedded applications. Now in its 4th decade of continuous use and enhancement, its reliability and performance underpin the firmware in every J-Link and J-Trace. embOS is available for all popular cores, compilers and development tools and has been deployed in several billion devices in a wide range of application areas.
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.
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.
Key features
- Powerful & easy-to-use API
- High performance with low memory use
- Kernel awareness plugins available
- Zero interrupt latency
- MISRA-C:2012 compliant
- Code base for functional safety certified edition embOS-Safe
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, IEC 62304 Class C, and ISO 26262.
Internet of Things
embOS is designed for ultra low power consumption and 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.).
Industrial controls
embOS is an essential component of every industrial control – especially in applications where functional safety and deterministic behavior are mandatory.
Automotive
The certification according to ISO 26262 makes embOS the perfect real-time operating system for your automotive environment whether it is used inside an ECU or for dashboard applications.
Medical devices
embOS-Safe is the ideal solution for every medical device. The embOS certification according to IEC 62304 Class C ensures the safety of medical products.
Avionics
Engineers building aerospace systems know that they can rely on the certified embOS-Safe for the foundation of their safety-critical products.

embOS RTOS packages — Object and source code
The real-time operating system (RTOS) embOS can be delivered as object code or source code package. The source code package extends the object code package by including the embOS source code. Using embOS source code enables the use of application specific compiler options. Compile time switches allow for customization of embOS by enabling only required functionalities. Adding embOS source code to the project provides additional insight when debugging at source-level.
Both embOS packages include the same ready-to-go board support packages for various devices and evaluation boards.

Licensing
embOS is available under various Embedded Software License models and delivered in source code packages. With a wide range of licensing options, embOS can fulfill commercial requirements as well as technical requirements. All licenses are one-time payments. embOS is royalty-free and not subscription-based. This makes the software a part of the equipment expenses, keeping the costs static.
The embOS licenses include:
- 6 months of updates and support by SEGGER's Embedded Experts
* Applies to second seat/product and all additional seats/products of the Single Product License and Single Developer License.
Friendly License
The object code package is available under SEGGER's Friendly License (SFL). This means, embOS evaluation and non-commercial use is unrestricted.
It can easily be downloaded for each embOS port from https://www.segger.com/downloads/embos/.
