PID控制器的verilog实现，做闭环控制器的人可以参考(PID controller verilog implementation of closed-loop controller may make reference to)

此功能是实现曼彻斯特编码的Verilog代码，经过在xilinx sp6上实际运行证实可行。(This function is to achieve the Manchester code Verilog code, through the Xilinx SP6 actual operation proved.)

VHDL语言写的频率计的程序，内带完整的技术报告-VHDL write the frequency of procedures, brought integrity of the technical report

VHDL写的串口，很好用，程序非常简单，可以调试用-Written in VHDL serial, very good, and the procedure is very simple, you can debug with

VC++6.0软件生成Altera公司FPGA内部存储器ROM初始化数据mif格式文件。方便通过QuartusII导入波形等参数。强调这个是例子，生成的是一个定点的正弦数据表文件，需要用到的请自行修改源代码。(This software generates internal memory ROM initialization mif format data file for FPGA product by Altera. Facilitate the passage of the waveform parameters such as import QuartusII)

三十个vhdl源码，对于刚开始学习vhdl的很有帮助，可以帮助理解数字电路-30 vhdl source for the beginning of the study vhdl helpful, and can help to understand digital circuit

基于fpga和51单片机的等精度频率计，通过fpga对信号进行采集，数据传给单片机计算，再由12864进行显示，可进行频率，周期，脉宽，占空比，幅值等的测量。(Fpga and 51 microcontroller based precision frequency meter, through fpga for signal acquisition, data to the microcontroller to calculate, and then by 12864 for display, can be measured frequency, period, pulse width, duty cycle, the amplitude and the like.)

verilog写的39阶通带为20KHz的半带fir滤波器，经测试正确。(verilog halfband FIR)
