键盘接口电路的一个工程

说明：  基于FPGA的游戏实例，开发板为Xilinx的basys3，VGA显示(Basys3, VGA Display of Xilinx Development Board Based on Game Example of FPGA)

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

基于FPGA的相位测量原理图，通过对正弦信号过零比较进入FPGA，测量相位差。可用于测量导纳等应用中。

基于quartus 的一些程序 都是verilog 还是比较有用的 -Based on some of the procedures Quartus Verilog are still quite useful
