Cléopatre: Open-source Operating System Facilities for Real-Time Embedded Applications

In this paper, we present the facilities offered by Cléopatre, a new framework devoted to respond to real-time application developers needs, more particularly for open source environments. The optional components of the operating system library cover a large range of needs in terms of scheduling, synchronization, fault-tolerance and aperiodic task servicing. And we describe some results of a performance evaluation study focusing on overhead and footprint
