10. Concluding Remarks

About a decade ago, networks-on-chip emerged from a potential solution for the intra-chip communication problems arising in complex systems (Guerrier and Greiner 2000), to a major research topic with its specific conferences (NoCs 2011; NoCArch 2011) and then to an industrial reality (Karim et al. 2002; Goossens et al. 2005). A huge amount of works have been proposed on design oriented features of NoCs, creating equally large NoC design diversity (Bjerregaard and Mahadevan 2006). Nevertheless, efficient test and reliability approaches are required to turn NoC-based systems into a consolidated industry reality and to achieve much more challenging designs such as many-core systems. As a matter of fact, a considerable amount of effort has been made towards an economically viable, testable, and reliable NoC-based system. The increasing interest in the topic has motivated the writing of this book, where we have put together and organized such large amount of material, summarizing the most relevant scientific contributions, and identifying some open issues. The final chapter of this book addresses the open issues.
