Abstract:

Based on the study of the CORDIC algorithm,this paper uses pipeline processing to implement the CORDIC in hardware,which meets the requirement of real-time processing and high precision.Software simulation and hardware experiment have been done for this module on Altera FPGA.The wide angle even above 360° can also be supported by the hardware module.The accuracy of most of the data is up to 10^-9,and the clock frequency reaches 233.2 MHz.The results show that the module has high accuracy and good stability.
