基于MCU和FPGA/CPLD结构的测频装置

Design and application of frequency-checking device based on MCU and FPGA/CPLD

给出了以单片机及基于单片机和CPLD相结合的两种方法实现的等精度数字测频装置,并给出了设计思想、原理框图和仿真波形。

Based on the special advantages of MCU and CPLD,which play an important part in electronic system design when combined with each other, this paper discussed two ways to realize the equal accuracy frequency-examining equipment with MCU and MCU &FPGA/CPLD,and provided the ideal of design,frame of principle and wave of simulation.
