Enea OSE is a compact, robust, high performance real-time embedded operating system with a modular architecture. It is based on a message-passing paradigm that is well suited for high integrity, distributed, and multi-core systems. It supports a multitude of extensions including file systems and communication technologies and has well developed support for qualities such as power management, fault management, and memory protection.

The Enea Hypervisor provides a virtual execution platform for multiple Guests, thus allowing several contexts (each that may include operating system, device drivers, and applications) to transparently operate in parallel. Thereby, several legacy non-multicore systems can be integrated on a new multi-core hardware platform.

Enea has a record of accomplishment that spans over more than forty years as a leading global provider of system software, development tools, and professional services for high-availability, mission critical embedded systems to the telecom, mobile, medical, automotive, and aerospace domain. Enea OSE has been on the commercial market since 1985, it is embedded in millions of devices around the world. Since 2009, Enea OSE supports SMP multi-core hardware architectures.

Patrik Strömblad is currently a Systems Architect in the CTO office at Enea and is also the Chief Architect for the OSE product line. He has been architecting and designing distributed real-time operating system kernels for 20 years, mainly focusing on the telecom application domain. His main focus now is on multicore software architectures and multicore programming techniques. He is also the inventor of the hybrid SMP/AMP technology used in OSE Multicore Edition.

Magnus Karlsson is currently a Systems Architect in the CTO office at Enea. His interests include real-time and general operating system design, multicore computer architectures, hypervisors and performance optimization techniques. Magnus has authored more than 30 papers in the fields of computer science and engineering and is the holder of a number of U.S. patents. He holds a Ph.D. (1999) from Chalmers University in Computer Engineering.
