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.)

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through

全数字锁相环的verilog源代码-全数字锁相环的verilog源代码

costas载波恢复算法 锁相环路，注释很清楚(costas carrier recovery algorithm PLL)

参数可配置的sequential 乘法器和booth 乘法器(verilog source code with configurable parameters for sequential multiplier and booth multiplier )

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)
