Abstract :
This paper presents a novel and simple sequential design of CORDIC for the calculation of Sine and Cosine of an angle. Design reduces the hardware requirement by using a single adder/subtractor module for all the iterations and for both Sine and Cosine calculation. Sequential design is implemented and synthesized in MAX plus 2 and time diagram is presented. A parallel extension is also discussed, which would increase the speed. Performance of the proposed design is compared with other general architectures available
