The pervasiveness of electronic computers has led the automotive industry to face new security and performance requirements to integrate new applications in the field. The modern reconfigurable logic circuits meet now the requirements of processing performance, flexibility and industry trends on reducing product cost. We show in our works the importance of new dynamically reconfigurable architectures in the automotive field and more generally in the area of dependability. The use of dynamically reconfigurable computers can reduce the number of computers and reduce the costs of implementation. Unfortunately, these architectures are very sensitive to radiation and therefore to errors. We propose in our work, low cost fault-tolerant mechanisms to solve this problem. By performing a fault detection on reconfigurable computers and coupling it with a mechanism of tasks migration (hardware and software), then it is possible to significantly increase the robustness of the system, while maintaining high degree of performance.
