Selex Sistemi Integrati activities will be presented, in particular about radar products and related processing technologies. The European Project SMECY (Smart Multicore Embedde System) and the results of the collaboration on CeCoNo (Cell Computing Node) Project will be described. The CeCoNo activity consists in the parallel design and realization of some high-performance critical sections of the STAP environment for radar processing, applying the methodology of the High-Performance Lab of the Computer Science Department.
