开源软核处理器OpenRisc的SOPC设计

Code VHDL for control VGA FPGA: Xilinx, Altera

0到255任意整数半整数分频Verilog HDL.rar-0-255 arbitrary integer half-integer frequency division Verilog HDL.rar

四位拨妞开关作为输入，当输入值变化时将其转化成两位输出(The four DIP Niu switch as an input, when the input value changes, be converted into two output)

n bit generic shift registers

xilinx spartan 6 pcie 仿真教程，v2.4版本，主要是讲解如何使用pcie core和自己的用户逻辑级联仿真。(xilinx spartan 6 pcie sim tutorial ，tell readers how to sim using pcie core and user app logic,tool:questasim)

spi通用串行总线，4线控制，可读写操作(SPI universal serial bus, 4-wire control, readable and writable operation)

user_logic_VGA_Controller，适合于DE2开发板，把这个文件夹放在工程目录之中，就可以在SOPC里直接添加VGA_Controller IP核了，很方便使用。-user_logic_VGA_Controller. suitable for Dictyophora development board, this folder on the project directory, it can be added directly SOPC Lane VGA_Controller IP core, very convenient to use.

说明：  这是一个用Verilog语言编写的一组程序，主要是熟悉开发板的应用，以及verilog语言(This is a Verilog language with a set of procedures, mainly familiar with the application development board, and the verilog language)

浮点数 矩阵乘法模块 verilog语言编写 可直接调用(Floating-point matrix multiplication module can directly call verilog language)

在Qaurtus环境下用Verilog输入实现64QAM信号的发生，用MATLAB协助验证，观察了PN序列对应的星座图。(Simulating generation of 64QAM RF Signal in Quartus II IDE,identified with MATLAB,constellation gram displayed.)
