An Optimized Maximum Approximation Angle CORDIC Algo ri thm Improvement

The paper proposes an optimized maximum approximation angle CORDIC algorithm improvement,low through maximum approximation angle of highest non zero binary calculation method, structure to achieve high though high -speed binary adder.Using micro-rotation angle recoding for low binary of the angle,pipelined manner not only makes easy to implement,but also to determine the direction of rotation,while reducing the number of iterations and increase the iteration speed,the higher the accuracy the more obvious advantages.The algorithm does not require ROM,significant saving in hardware resources,can be applied in the field of precision high-speed arithmetic.
