The latest generation of many-core processors offers more than ever the opportunity to pool different applications into a single embedded system. This opportunity however depends on the ability to provide safety guarantees, especially when it comes to embedded life- or mission-critical applications. For that matter, we introduce a new multi-task preemptive micro-kernel for many-core architectures called Psigma. This micro-kernel is able to run simultaneously and safely tasks written with very different programming paradigm, and very different execution requirements: hard real-time applications and stream applications. This paper shortly presents both programming models, then focuses on the design and performances of the micro-kernel.
