Design and implementation of an Adaptive Pipelined CORDIC Architecture for Wireless Communication System on FPGA Platform

An adaptive pipelined Coordinate Rotation Digital Computer (CORDIC) architecture for high-speed FPGA-based Wireless communication applications is presented in this study. A 16-bit fixed-point datapath and an adaptive iteration control mechanism are used in the suggested architecture, which dynamically modifies the number of active CORDIC iterations in accordance with the necessary computing accuracy. The suggested design uses adaptive iteration and bypass logic to remove unnecessary calculations while keeping a fixed pipeline depth, in contrast to traditional pipelined CORDIC implementations. The design is implemented using Xilinx ISE 14.7 on an Artix-7 FPGA and written in Verilog HDL.  A maximum operating frequency of 420.026 MHz, a throughput of 480.029 Mbps, and hardware usage of 672 slices and 1709 LUTs are all shown by experimental results. Functional verification confirms that the suggested design offers an effective trade-off among speed, area, power, and numerical accuracy for real-time DSP and wireless communication systems, achieving around 99.99% computational accuracy.
