ChorusOS

ChorusOS is a microkernel real-time operating system designed as a message-based computational model. ChorusOS started as the Chorus distributed real-time operating system research project at Institut National de Recherche en Informatique et Automatique (INRIA) in France in 1979. During the 1980s, Chorus was one of two earliest microkernels (the other being Mach) and was developed commercially by Chorus Systèmes. Over time, development effort shifted away from distribution aspects to real-time for embedded systems.
