Voltage pulse control of a project

KDP晶体二倍频与三倍频；基于耦合波方程组；已于实验结果校核 (Sum Frequency in KDP)

如果不考虑占空比，直接利用计数器来进行分频，则占空比会发生变化。下面程序实现1：1的三分频。-if not duty cycle directly counter to the use of sub-frequency, duty cycle will change. Below a program : a third of the frequency.

verilog实现DLX指令集5段流水线(5 stage DLX pipeline implemented in verilog)

此程序用通过PFGA用VHDL语言实现了傅立叶变换，希望对大家有用

应用背景此应用程序是用Xilinx ISE 12.4，使用VHDL语言进行。本程序的目的是提供一个显示的接口方法的七段显示。用户将可以看到从0到9999的一个计数器，它运行在利用FPGA内部的时钟实时。享受它。关键技术现场可编程门阵列（FPGA）是半导体器件是基于一个可配置逻辑块（CLB）连接矩阵通过可编程互连。FPGA可编程所需的应用或功能要求后制造。这功能区分FPGA从特定应用集成电路（ASIC），这是制造的特定设计定制任务。虽然一次性可编程（OTP）FPGA，这主要类型是基于SRAM的可重新编程的设计演变。

Xilinx CPLD源代码，使用XC9500系列CPLD,驱动液晶-Xilinx CPLD source code, use the XC9500 series CPLD, LCD Driver

vhdl code for obtaining video output through vga port

Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.

VERILOG设计实例，非常详细的例子，有交通灯，频率计，数字跑表等等例子(Verilog design example, a very detailed examples have traffic lights, frequency meter, digital stopwatch, etc. Examples of)
