This book has a detailed review on CORDIC algorithm. It's VLSI Architecture, VHDL Implementation and Application as DFT implementation. I want to dedicate my work to my parents and family members whose constant encouragement and blessings have kept myself motivating to write this book. I am also thankful to the authors whose works I have consulted and quoted in this work. Last, but not the least, very special thanks to my friends for their patience and understanding without which this study would not have been in this present form, is greatly appreciated.
