Abstract :
A Code-Division Multiple Access (CDMA) based on-chip communication network is proposed in this paper. The proposed design features a novel encoding and decoding scheme for CDMA transmission which improves area, latency and power dissipation of the network on Chip (NoC). The orthogonal and balance properties of Walsh codes are used for the routing of data between the resources on the network. The proposed CDMA encoding and decoding schemes are compared with the conventional schemes. The overall area required to implement the proposed CDMA NoC design is reduced by 54%. The design decreases the latency of the network by 48.2%. The total power consumption required to achieve the proposed design is decreased by 54.8%.
