用VERILOG实现一个被除数为8位、除数为4位的高效除法器(With VERILOG implement a dividend for the 8-bit, 4-bit effective divisor divider)

lvds transmitter megafunction (lvds transmitter megafunction)

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

说明：  KMP算法的Verilog HDL实现，模式串从模块的外部输入，计算next函数，然后进行KMP匹配。有仿真。环境为Quartus II 8.0 Web Edition。(Verilog HDL implementation KMP algorithm, pattern string from the module' s external input, calculate next function, then KMP matching. A simulation. Environment for the Quartus II 8.0 Web Edition.)

ＦＰＧＡ设计中的一些经典例子对学习ＦＰＧＡ的人会有帮助-FPGA design of some of the classic examples of people learning FPGA would be helpful

在Quartus环境中，采用VHDL语言编写的出租车计费系统，系统共分为分频、状态切换、记程、计费等模块，模仿现实中出租车计费。-In the Quartus environment, the use of VHDL language taxi billing system, the system is divided into sub-frequency, state switching, recording process, billing and other modules, to imitate reality, taxi billing.

DDR2-400样例源代码，用于Xilinx Spartan 3A/3AN Starter Kit(DDR2-400 sample source code for Xilinx Spartan 3A/3AN Starter Kit)

运用VHDL语言编写的检测1111的序列检测代码和加法器，运用verlog语言的交通灯，流水灯，出租车自动计费器等
