运动员反应时间测量电路

自己用verilog编写的urisc程序，调试成功，压缩包里有仿真图像，值得学习参考。(Written in verilog urisc program debugging, simulation image compression bag, worth learning reference.)

三八译码器，四位加法器，EDA实验，用verilog编写(EDA experiment with verilog language)

实现在屏幕上显示绿色和红色相间的水平条纹。其中，vga_640x480模块将产生行同步信号hsyn和场同步信号 vsync; vga_stripes模块将产生red、green和blue三个输出。(The horizontal stripes of green and red are displayed on the screen. Among them, vga_640x480 module will produce line synchronization signal Hsyn and field synchronization signal vsync; vga_stripes module will produce red, green and blue three outputs.)

ADC Reference code!Clock 100kHz

此源码为线性相位滤波的vhdl源码与设计心的体会，理论分分析与工程实践总结相结合，有非常大的参考价值 可直接使用。 (The source for the linear phase filter VHDL source code and design of the heart experience, theoretical analysis to summarize the combination of engineering practice, a very large reference value can be used directly.)
