Network-on-Chip Xilinx Implementation of WBCDMA System and Its AWGN Performance Analysis S. Rama Devi , T. Vedavyas, and M. Satya Anuradha Abstract Communication is a solution to achieve data transfer between various system components. In this paper, an efficient Walsh-code-based code division mul- tiple access (WBCDMA) was implemented. The encoder and decoder blocks are developed using Walsh-code-based orthogonal codes. An eight-node WBCDMA network was developed and synthesized. WBCDMA Network-on-chip communica- tion is realized by using Xilinx ISE 14.7 edition. The area requirements are obtained from the synthesis report and using Vivado estimation tool. The power requirements are analyzed. This paper also concentrates on the real-time applicability of the system that is possible with the help of mixed-signal processing. Xilinx system generator is used to analyze BER performance of the above system under AWGN channel condi- tion. The simulation reveals that the 8-bit data can be simultaneously transferred to the corresponding nodes without the loss of information. The WBCDMA NoC data transfers latency of 20. The power requirements are also minimized (Ahmed et al. in IEEE Trans Very Large Scale Integr (VLSI) Syst 25(6), 2017). Noise impact on the data transfer between different nodes is almost negligible when SNR crosses above 20 dB. These systems can be used to validate the real-time implementation.

Network-on-Chip (NoC) is proposed to solve the on-chip communi- cation problems. Circuit-switched network, packet switching network, is the most S. Rama Devi (B ) · T. Vedavyas · M.
