利用CORDIC算法提取脉内特征在FPGA上的实现
Implementation of FPGA-based CORDIC algorithm used to extract in-pulse characteristics
摘要
Abstract
The principle of the coordinated rotation digital computer(CORDIC)algorithm is introduced. The iterative formula of the signal in⁃pulse characteristics extracted by CORDIC algorithm is proposed. On this basis,the FPGA circuit of extracting the instantaneous amplitude,phase and frequency by pipeline iterative structure of the algorithm was realized. The problems of clock and register configuration,data′s complementary code format and phase accumulation in the circuit were solved. The down⁃loading verification on hardware chip shows that the circuit structure is reasonable,and test is effective. The circuit can satisfy the design requirement.关键词
