1、用状态机设计A/D转换器ADC0809的采样控制电路，并在数码管上显示转换结果； 2、设置有复位和启动/保持开关，要求 ⑴ 复位开关用来使A/D转换器复位，并做好A/D转换准备； ⑵ 启动/保持开关用来控制A/D转换器开始连续转换或停止转换保持结果，即按一下启动/保持开关，启动A/D转换器开始转换，再按一下启/停开关，停止转换并保持结果。 3、采用Verilog HDL语言设计符合上述功能要求的控制电路。(1, with the state machine design A/D converter ADC0809 sampling control circuit and display the results on the digital conversion 2 is provided with a reset and start/hold switch, reset switch is used to make the request ⑴ A/D converter reset and do A/D conversion ready ⑵ start/hold switch is used to control the A/D converter starts converting or stop the conversion to maintain a continuous result that by clicking Start/hold switch, start the A/D converter to start the conversion, and then Click the start/stop switch stops the conversion and keep the results. 3, using Verilog HDL language designed to meet the functional requirements of the above-mentioned control circuit.)

niosII的ip核的实现原理讲解，讲解的非常详细。(niosII ip nuclear realization of the principle of explanation, to explain in great detail.)

这是一个二进制的最简单分频器，是一个简短的fpga代码，用verilog书写(This is the most simple of a binary frequency divider, the fpga is a short code, written in verilog)

利用VHDL语言设计一个分频器，输入为CLK,输出分别为CLK1、CLK8、CLK256、 CLK1024-The use of VHDL language design a divider, input CLK, the output respectively, CLK1, CLK8, CLK256, CLK1024
