Major drawback of bus based communication system is that the loading effect becomes more if the complexity of the system is increased which drops the speed further. Ad-hoc routing of wires results in backend complications, lower performance and higher power consumptions. Network on Chip (NoC) has been adopted as a new promising solution for its extensibility and power efficiency. The fundamental unit of Network on Chip is the router. In this paper, we proposed a router module with wormhole switching concept. The router module is described at RTL level using VHDL and simulated in Xilinx ISE 13.1 simulator.

Keywords: System on Chip, Network on Chip, Routers, Switching Techniques, Arbitration.
