Network on Chip (NoC) has emerged as a competitive and efficient communication infrastructure for the core based design of System on Chip. Resource (core), router and interface between router and core are the three main parts of a NoC. Each core communicates with the network through the interface, also called Resource Network Interface (RNI). One approach to speed up the design at NoC based systems is to develop standardized RNI. Design of RNI depends to some extent on the type of routing technique used in NoC. Control of route decision base the categorization of source and distributed routing algorithms. In source routing a complete path to the destination is provided in the packet header at the source, whereas in distributed routing, the path is dynamically computed in routers as the packet moves through the network. Buffering, flitization, deflitization and transfer of data from core to router and vice versa, are common responsibilities of RNI in both types of routing. In source routing, RNI has an extra functionality of storing complete paths to all destinations in tables, extracting path to reach a desired destination and adding it in the header flit. In this thesis, we have made an effort towards designing and prototyping a standardized and efficient RNI for both source and distributed routing. VHDL is used as a design language and prototyping of both types RNI has been carried out on Altera DE2 FPGA board. Testing of RNI was conducted by using Nios II soft core. Simulation results show that the best case flit latency, for both types RNI is 4 clock cycles. RNI design is also resource efficient because it consumes only 2% of the available resources on the target platform.
