FPGA-Based Design of High-Speed CIC Decimator for Wireless Applications
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2011, Vol 2, Issue 5
Abstract
In this paper an efficient multiplier-less technique is presented to design and implement a high speed CIC decimator for wireless applications like SDR and GSM. The Cascaded Integrator Comb is a commonly used decimation filter which performs sample rate conversion (SRC) using only additions/subtractions. The implementation is based on efficient utilization of embedded LUTs of the target device to enhance the speed of proposed design. It is an efficient method used to design and implement CIC decimator because the use of embedded LUTs not only increases the speed but also saves the resources on the target device. The fully pipelined CIC decimator is designed with Matlab, simulated with Xilinx AccelDSP, synthesized with Xilinx Synthesis Tool (XST), and implemented on Virtex-II based XC2VP50-6 target FPGA device. The proposed design can operate at an estimated frequency of 276.6 MHz by consuming considerably less resources on target device to provide cost effective solution for SDR based wireless applications.
