Huang Shou-li · Microcomputer Information · 2008
This paper first introduces the principle of CORDIC algorithm and orthogonal modulation technology,then it gives detailed analysis of pipelining CORDIC kernel cores and processor unit for the design,a new way of orthogonal signal generator based on pipelining CORDIC is proposed. Based on the traditional CORDIC algorithm,it improves the calculation precision through using pipelining technology and optimizing the arguments,making the orthogonal triangle function adapted to higher precision required occa-sion. Finally programming and designing the CORDIC,carries out the function simulation and timing simulation,downloading it to the FPGA,the result shows that it has a great practicability.
