Problems and challenges of emerging technology networks−on−chip: A review

Networks−on−chip (NoC) are an alternative to alleviate the problems of legacy interconnect fabrics. However, many emerging technology NoC are developed and are now seen as their potential substitutes. In this context, this work introduces how the NoC industry is involved in the NoC technology design−trends and promotion. Secondly, an extensive discussion on the outstanding research problems and challenges for conventional and emerging technology NoC is developed. The related security concerns are particularly investigated.
