Dynamic resource allocation has a significant impact on the performance of MPSoCs (Multiprocessors System-on-Chip) based on Networks-on-Chip (NoCs). In this work, we propose the IPNoSys III, an NoC using Software Defined Networks (SDN) paradigm applied to IPNoSys, a parallel non-conventional architecture. IPNoSys III has a 2D mesh topology, that contains in each node four processing cores, connected to a memory and that run packages in the IPNoSys format, and a communication unit. An SDN controller, connected to all nodes, manages the network and has an overview of the network to execute the routing algorithm and to map tasks according to the performance objectives. The results show up to 17% better performance in clock cycles to the SDN controller than a static solution and up to 46% better when comparing IPNoSys III to a conventional NoC.
