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.
