The Operating System Embedded (known by the acronym Enea OSE) is a real-time embedded operating system created by the Swedish information technology company ENEA AB. Bengt Eliasson, who at the time was a consultant from ENEA with an assignment at Ericsson, wrote the basic parts of the kernel. The early version for the Zilog Z80 processor was named OS80.
OSE uses events (named signals due to ENEA's telecom background) in the form of messages passed to and from processes in the system. Messages are stored in a queue attached to each process. A 'link 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 an open-source inter-process kernel design project called LINX.
Enea OSE Multicore Edition was released in 2009 and is based on the same microkernel architecture. The kernel design that combines the advantages of both traditional asymmetric multiprocessing (AMP) and symmetric multiprocessing (SMP).
The hybrid AMP/SMP kernel in OSE Multicore Edition is based on a number of:
The Enea OSE family of RTOS features 3 OSs: OSE for ARM processors, PowerPC and MIPS, OSEck for various DSP's, and OSE Epsilon for minimal devices, written in pure assembly(ARM processors, ColdFire) .
OSE supports many mainly 32-bit processors:
