FPGA Based Design of Digital Wave Generator using CORDIC Algorithm

In this paper an efficient approach is presented to design and implement a high speed and areaefficient Digital Sine and Cosine Wave Generator for wireless applications like SDR and GSM. The implementation is based on Coordinate Rotation Digital Computer (CORDIC) algorithm which uses shifts, additions and a very small lookup table (LUT). It is an efficient method used to compute trigonometric functions, multiplications, divisions, data type conversions and hyperbolic functions in a simple and elegant way. The proposed design is synthesized with ISE 10.1isoftware, simulated with Modelsim 6.3XEsimulator and implemented on Spartan-3 FPGAtarget device using Chipscope 10.1. Results show enhanced performance using proposed CORDIC algorithm in terms of speed, area and power utilization.Key Words: FPGA, CORDIC, Simulation, VHDL, Pipeline
