FPGA控制AD逐点采集信号，并将AD转换后的数据串行发送出去。

通过VERILOG编写的AD9516时钟芯片SPI配置代码(CONGIGURE THE ad9516)

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

此设计采用Verilog HDL硬件语言设计,在掌宇开发板上实现. 将整个电路分为两个子模块，一个提供同步信号（H_SYNC和V_SYNC）及像素位置信息；另一个接收像素位置信息，并输出颜色信号。这样便于进行图形修改，同时也容易实现- This design uses Verilog the HDL hardware language design, realizes on the palm space development board Divides into two stature modules the entire electric circuit, provides the synchronized signal (H_SYNC and V_SYNC) and the picture element positional information; Another receive picture element positional information, and output color signal. Like this is advantageous for carries on the graph to revise, simultaneously is also easy to realize

请注意： 本例的源描述包含文件类型，在学习版上不能编译及模拟， 如果您需要对此描述进行编译及模拟，请与北京理工大学 ASIC研究所联系。 另外，此例与第75例是同一个电路的不同部分的描述，可以 一起参考这两个例子的描述。-Please note : The cases include the description of the source file type, version of the study can not be compiled and simulation, if you need to compile this description and simulation, Beijing Polytechnic University and the Institute of ASIC link. Additionally, the cases of 75 cases with the first of a circuit with the different parts of the description, reference together two examples of this description.

This tutorial explains how the SDRAM chip on ltera’s DE2 Development and Education board can be used with a Nios II system implemented by using the Altera SOPC Builder.

数字电压表的实现，VHDL语言实现，AD采用TLC549，通过学习，了解AD采集过程(The realization of digital voltage meter, VHDL language, AD using TLC549, by learning to understand the acquisition process AD)

一个在FPGA芯片上实现UART功能的vhdl源代码，提供了UART的集成-an FPGA chip to achieve UART function vhdl source code, providing integrated UART

最近组长给分配的任务，这几天一直在做，比较郁闷的是用的器件是XC400XL系列的，只有ISE4.1支持，用惯了7.1i的我还是要适应一阵子（关键4.1是一个试用版的）。挺折腾的，不说了，放上顶层模块：-。。。
