Network on Chip with CDMA Technique

NoC (network On Chip) is an efficient approach to design the communication subsystem between IP Cores in SoC (System on Chip). In this paper a communication infrastructure design using CDMA (Code division multiple access) based shared bus architecture for core-to-core communication in NoC is presented. CDMA has been proposed as an alternative way for interconnect of IP cores in a SoC design, or as a solution for interconnecting modules within a system realized in several PCBs. Compared to a conventional TDMA-based bus this paper present how a multiprocessor system can benefit from the use of concurrent data transfers. The simulation of the system using VHDL code is carried out. The performance of the system and is evaluated.
