The aim the talk is presenting my research contributions in the context of network-on-chip (NoC) architectures. I will cover four main topics, including, routing algorithms, mapping techniques, data encoding, and approximate communication. Specifically, a methodology for designing application specific routing algorithms will be presented. In this context, emphasis will be devoted on a set of selection policies aimed at i) managing partially faulty links and ii) improving the adaptivity of multi-path routing algorithms. A multi-objective design space exploration technique aimed at optimizing the power vs. performance trade-off by exploring the mapping and the routing design spaces will be presented. Finally, two main techniques aimed at improving the energy efficiency of NoC based systems will be introduced. The first one, is based on data encoding for minimizing the switching activity of the NoC links. The second one extends the approximate computing paradigm to the communication sub-system with the aim of trading-off communication energy efficiency with the quality of the application outputs.
