Implementation of Pipelined CORDIC based on FPGA

CORDIC can convert the complex operations,which are hard to be directly implemented by hardware circuit,into the simple adding and shift operations,then gradually approach the exact result.It keeps balance between precision,speed and hardware complexity,and thus is widely used in the digital signal processing field.The author first gives the principle of CORDIC,then the implementation of pipelined CORDIC based on FPGA.The results indicate that the output errors are minor and the simulation results are fairly accorded with the theoretical value.
