基于单片机与FPGA的等精度数字频率计设计

Design of Precision Digital Frequency Meter Based on SCM and FPGA

根据等精度的测量原理,利用单片机与FPGA编程设计了一种数字频率计,系统将测控主体分配给FPGA,可以满足测频速度和I/O口的要求;同时利用单片机良好人机接口和控制运算的功能,来达到较简单地实现键盘和显示控制及数据处理的能力。在实际应用中既能满足测量精度的要求,又有很好的性价比。

According to the accuracy of the measuring principle, using single chip computer and FPGA programming to design a digital frequency meter,the system will control subjects assigned to FPGA,can satisfy the measurement speed and I/O export requirements;at the same time using singlechip good man-machine interface and control operational functions,to achieve a simple implementation of keyboard and display control the ability of data processing.
