Abstract :
In modern computer systems (communication systems, military systems, medical applications, etc.) are sophisticated mathematical operations and trigonometric calculations widely used. CORDIC (Coordinate Rotation DIgital Computer) architecture should be used on digital computers to implement complex mathematical operations and trigonometric calculations. In this study, two architectures called FP-CORDIC and IQCORDIC have been devised to implement CORDIC algorithm. These architectures have been realised with IEEE-754 and IQ-Math in order. Also they have been compared according to execution time, process accuracy and hardware performance criteria on FPGA.
