A co-design space exploration tool for avionic high performance heterogeneous embedded architectures

Avionics in the helicopter manufacturers' landscape faces new challenges. Whereas customers raise continuously their needs in terms of new functions and embedded systems performances, certification authorities maintain complex rules to fulfill for parallel computing. This constraining situation has conducted avionics professionals to consider heterogeneous architectures for avionics as a growing trend. The complexity of such architectures combined with the large number of embedded applications to integrate puts under light the need of new approaches to optimize the mapping of task on heterogeneous processing. In the present paper, we explain how a co-design method could meet avionics requirements with a specific co-design architecture exploration and the task's granularity tuning. An implementation of the proposed avionics co-design system is also proposed.
