CDMA Coding Techniques for Interconnect Between IP Cores

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 CDMA (Code Division Multiple Access)bus is proposed as a communication interconnect for different IP cores. 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.
