摘要：

Coordinate Rotation Digital Computer (CORDIC) algorithm is an established method in complex arithmetic function discovery using shift and add operations. An absolute Scaling-free CORDIC algorithm for cosine and sine function computation function has been implemented. A combination of third order approximation Taylor series and leading-one-bit detection algorithm has been adopted in this implementation. Seven (7) iterations were required for a 16-bits iterative architecture implementation of the proposed algorithm. The synthesis result shows that the algorithm is suitable for high-speed computational applications.
