Services matériels pour des systèmes multi processeur temps réel [Hardware services for MPSoC with real-time operating systems]

Services matériels pour des systèmes multi processeur temps réel [In recent years we have witnessed a paradigm shift in computer systems. Increasing the frequency has given way to multi-core architectures exploiting the parallelism. In the field of embedded systems, such a vision is seen in the form of Multi-Processor System-on-Chip - MPSoC. The advantages of such a platform in comparison with a uni-processor one are multiples in several domains like power consumption, scalability and reusability. In the same time, a lot of existing systems need Real Time Operating Systems not only to guarantee a given treatment capacity but also to guarantee a deadline for multiple tasks. To break with the sub-optimality of the actual philosophy consisting to see the design of software and hardware as two worlds apart, the aim of this thesis is, through a co-design methodology, to design a configurable MPSoC environment with services tailored directly for high level real-time scheduling algorithms.]
