一个vhdl实现的hamming码编码器

fpga正弦波发生函数，可用于自动生成rom文件(fpga sine wave generating function)

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.

Quartus II 7.2环境中，采用硬件描述语言VHDL独立完成了基于MIPS指令集的32位RISC处理器的逻辑设计(quartusII mips pipeline 32bit cpu design)

说明：  本工程使用A7系列FPGA产生DDS，用DAC0832进行正弦电压输出(In this project, A7 series FPGA is used to generate DDS, and DAC0832 is used for sinusoidal voltage output)

8b10b编解码，用于光通信和千兆以太网，verilog编写，已验证(8b10b codec for optical communications and Gigabit Ethernet, verilog prepared Verified)

基于FPGA的VGA控制器，可在屏幕显示彩色条纹(A vga controller based on FPGA)

用游戏把子上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，等到了一定的分数，就能过关，然后继续玩下一关。
