In recent research papers being carried out, there are numerous applications where sine and cosine waves are used. Also, there are a wide variety of ways to generate digital sine and cosine waves, but it requires excessive memory usage when good quantization level is needed. On the other hand, CORDIC (CO-ordinate Rotation DIgital Computer) algorithm offers an excellent alternative which has greater flexibility and quantization accuracy as a function of word length. It is a multiplier-less approach which uses only shift and add operations to estimate the basic elementary function thus, is more economical than DSP algorithms in terms of area and power consumption.
