Enea AB is an information technology company with its headquarters inKista, Sweden, that providesreal-time operating systems and consulting services. Enea, which is anabbreviation ofEngmans Elektronik Aktiebolag, also produces the OSE operating system.
Enea was founded 1968 by Rune Engman asEngmansElektronikAB. Their first product was an operating system for a defence computer used by theSwedish Air Force. During the 1970s the firm developed compiler technology for theSimulaprogramming language.
During the early days of the European Internet-like connections, Enea employeeBjörn Eriksen connected Sweden toEUnet usingUUCP, and registeredenea as the first Swedish domain in April 1983. The domain was later converted to the internet domainenea.se when the network was switched over toTCP and the Swedish top domain .se was created in 1986.[2][3]

The ENEA OSEreal-time operating system first released in 1985.[4]
The Enea multi core family ofreal-time operating systems was first released in 2009.[5]
The Enea Operating System Embedded (OSE) is a family of real-time,microkernel,embedded operating system created by Bengt Eliasson for ENEA AB, which at the time was collaborating withEricsson to develop amulti-core system usingAssembly,C, andC++. Enea OSE Multicore Edition is based on the same microkernel architecture. The kernel design that combines the advantages of both traditionalasymmetric multiprocessing (AMP) andsymmetric multiprocessing (SMP). Enea OSE Multicore Edition offers both AMP and SMP processing in a hybrid architecture. OSE supports many processors, mainly32-bit. These include theColdFire,ARM,PowerPC, andMIPS basedsystem on a chip (SoC) devices.
The Enea OSE family features three OSs:OSE (also namedOSE Delta) for processors byARM,PowerPC, andMIPS,OSEck for various DSP's, andOSE Epsilon for minimal devices, written in pure assembly (ARM,ColdFire,C166,M16C,8051). OSE is a closed-sourceproprietarily licensed software released on 20 March 2018. OSE usesevents (orsignals) in the form of messages passed to and fromprocesses in the system. Messages are stored in aqueue attached to each process. Alink handler mechanism allows signals to be passed between processes on separate machines, over a variety of transports. The OSE signalling mechanism formed the basis of anopen-source inter-process kernel design project named LINX.[6]
