Network-On-Chip (NoC) is the most scalable in- terconnection paradigm that is capable of addressing various application needs. In NoCs, data are treated as packets, while processing elements as nodes that are interconnected via routers and switches. As the number of processing elements in a System On a Chip increases the desired performance cannot be achieved by the traditional bus based architecture. As a result packet switching concept (NoC) can be used for the communication between the processing elements. When different processing elements communicate through the same physical link there arise collisions. Collisions are avoided by using Code Division Multiple Access (CDMA) as the medium sharing technique. The basic building block in NoC is a crossbar. Crossbar consists of encoder, adder and a decoder section. Information between the processing elements is transmitted either as ones or zeros. This leads contention. This contention can be eliminated by using compression method. The technique of applying CDMA concept in NoC along with data compression technique is the point to be discussed in this work. The structure of CDMA NoC is proposed and the process is coded and implemented by using Xilinx software in this work.
