Research on phase locked loop based on DSP and CPLD
Zhang Zhong-chao · Mechanical & Electrical Engineering Magazine · 2007
A new method of digital phase locked loop based on digital signal processing(DSP) and complex programmble logic device(CPLD) was proposed.Firstly,the communication between DSP and CPLD was realized,and the basis of communication,the principle of digital phase locked loop was illustrated.Finally,the program algorithm and its process were given.The experimental results prove that the method has validity and feasibility,it illustrates a good prospect of application and extension.
