摘要: In the last decade, CORDIC algorithm has drawn wide attention from academia and industry for various applications such as DSP, biomedical signal processing, software defined radio, neural networks, MIMO systems to mention just a few. It is an iterative algorithm, requiring simple shift addition operations, hardware realization of basic elementary functions. Since used building block in single chip solutions, critical aspects be considered are high speed, low power, area, achieving reasonable overall performance. this paper, we first classify based on number system discuss its importance implementation algorithm. Then, present systematic comprehensive taxonomy rotational algorithms, which subsequently discussed depth. Special been devoted higher radix flat techniques proposed literature reducing latency. Finally, detailed comparison algorithms presented, can provide first-order information designers looking either further improvement performance or selection specific application.
