Richa Upadhyay, Nisha Sarwade, Shrugal Varde · 2013
In recent researches, there are countless applications where sine and cosine wave are used, like in Physics, Digital Signal Processing for various transforms, several modulation and demodulation techniques etc. There are numerous ways to generate digital sine and cosine waves, the use of previously calculated tables is one of the choices, but it requires excessive memory usage when good quantization level is needed. CORDIC algorithm, on the other hand, offers an excellent alternative, and its best characteristic is flexibility. Its quantization accuracy is a function of word length. In this paper a simple Pipelined CORDIC structure for generation of sine and cosine values has been implemented and verified using Simulink tool by MATLAB.
