On-chip interconnect networks causes congestion which affects the performance in current system-on-chips. Code division multiple access (CDMA) has rigid delay, trimmed intervention expense and superior transfer capacity. Because of this features, it’s been projected for On-Chip crossbars. In CDMA, the standard division is facilitated in the secret language bit by appointing a bounded quantity of unrelated(orthogonal) scattering codes of N chip range to the processing elements distributing the link. In the existing work overburden CDMA communicate (OCI) to improve the aptitude of CDMA based NoC (network-on-chip) crossbars by escalating the adding up to of good dispersion codes. In this paper, the overburden CDMA implemented and the normal adder is replaced with Han Carlson Adder (HCA) in OCI Crossbar at the time of addition. This extension of HCA gives high-speed parallel addition, reduction in power and area. Analogized with the existing OCI on a Cyclone-2 FPGA kit, the serial OCI attains greater transmission capacity, 30% less resource consumption, 25% power retaining and less delay, while the parallel OCI Crossbar attains N times greater transmission capacity, takes larger area and power. The OCI crossbar with HCA gives better results than the standard one.
