摘要：In recent times, power consumption and the area efficiency has become a challenge in designing Very Large Scale Integrated Circuits (VLSI). CORDIC (Coordinate Rotational Digital Computer) has come out as its solution in performing trigonometric elementary functions because of the fact that uses only shifters and adders. In this article, CORDIC potentiality is exhibited as it finds its applications in many streams like Communication, Digital Signal Processing and Image processing, angle rotation in hyperbolic, linear and circular coordinate systems, Vector transformation, scientific calculators, Robotics. The latency of Taylor series expansion to compute sine/cosine angles is also discussed. The Xilinx implementation of CORDIC is simulated and the overview of its applications in modern era is presented. The proposed paper explains the performance of CORDIC with the elimination of sine block in the initial stages as the sine of the smaller angles is negligible.
