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.
