    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...
