摘要
介绍以CPLD为虚拟频率计核,运用MAX+PLUSⅡ开发平台,在WINDOWS95/98下面DELPHI5.0实现人机交互界面,用PC机中CPU完成对外周期信号实现10^（-5）精度的智能化频率测量的VHDL设计思想和实现方案。
A virtual frequency meter is introduced with CPLD, the man-computer interface is realized with Delphi 5.0 in Windows 95/98. The cycle signals are tested intellectually by CPU in PC with the precision of 10^(-5) . The meter VHDL design idea and realizing plan are also given in the Max + plus Ⅱ .
