基于等精度测频法的频率计测频模块，用VHDL 编写，在QUARTUS里面编译成功的-Such as precision frequency measurement method based on the frequency meter measuring frequency module, using VHDL written inside the compilation of success in the QUARTUS

用FPGA实现等精度测频，比一般测量频率准确，这是控制FPGA的VHDL程序，测试过是好的，可以直接下载使用。-Frequency measurement precision

等精度测频VHDL 实现等精度测频功能 可预置闸门时间(VHDL Equal precision frequency measurement, VHDL implementation of equal precision frequency measurement function, preset gate time)
