Network on Chip (NoC) is a communication framework for on-chip network. NoC has implemented the concept of packet switching from data communication in on-chip network. NoC consists of multiple nodes Processing Elements (PEs) connected together through routers. Routers are in turns connected together through bidirectional interconnects. NI connects the PEs to routers as it separates the data communication of PE from network communication. © Medwell Journals, 2016.
