Abstract :
In this paper we present an optimisation of CORDIC algorithm implementation, which offers silicon area occupation reduction and gives good precision in calculating trigonometric functions such as sine and cosine functions. To validate the new method, an implementation of the angle decomposition equation using FPGA technology is presented. This approach shows a considerable surface reduction and good precision for calculation resolution less than 20 bits
