A dedicated micro-kernel to combine real-time and stream applications on embedded manycores

Conference of 13th Annual International Conference on Computational Science, ICCS 2013 ; Conference Date: 5 June 2013 Through 7 June 2013; Conference Code:103369International audienceThe 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
