Opis

CORDIC is a class of shift and add algorithms for rotating vectors in a plane, used for the calculation of trigonometric functions, multiplication, division and conversion between binary and mixed radix number systems of DSP applications, such as Fourier Transform.There are different types of modified CORDIC algorithms are developed to minimize the iteration ,to decrease execution time and area, and increases efficiency . The power speed and area are the important parameters On VLSI implementation level, the area also important as more area means more system cost. Since elementary functions calculation dominates the execution time of most DSP algorithms, so there is need for high speed CORDIC algorithm. Main drawback of CORDIC algorithm is that to converge to N bit of accuracy, N iterations are required. Therefore the execution speed is less as the iterations are more efficiency also decrease.
