 本程序应用VHDL硬件描述语言，以QuartusⅡ8.0为开发工具设计了一个具有自动演奏乐曲功能的系统，演奏乐曲为《梁祝》，具有单曲播放器功能。本程序简单易懂，可作为FPGA入门学习之用。

很不错的FPGA入门级实验指导书，按照实验的知道，能够学会使用ISE仿真简单的流水灯。教程较为详细，从硬件连接到代码编写都做了详细指导，适合新手入门。(Very good entry-level FPGA experimental guide books, according to the experiment know, be able to learn to use the ISE Simulator simple water lights. Tutorial in detail, the hardware connected to the coding have done a detailed guide for beginners.)

利用两个半加器来组成的全加器，是简单的vhdl语言入门-The use of two and a half adder to form the full adder is a simple entry-vhdl language

说明：  用FPGA于32进行SPI单向通信，FPGA向32放松发送数据(One-way SPI communication is carried out in 32 with FPGA, and data is sent to 32 with ease by FPGA.)

做EDA的，就不用介绍这个文件了吧，IEEE1364标准（开放）。-done, would not have introduced the document on the bar, IEEE1364 standard (open).

基于Xilinx Vertex2的可综合的2048x10位的读写可控制FIFO模块源代码，深度可控(Based on the Xilinx Vertex2 can be integrated 2048x10-bit read and write can control the FIFO module source code, the depth of controllable)

设计制作一个可容纳4组参赛者的数字智力抢答器，每组设置一个抢答按键； 电路具有一第一抢答信号的鉴别和锁存的功能。在主持人将系统复位并发出抢答指令后，若参加者按抢答键，则该组指示灯亮并用组别显示抢答者的组别。此时，电路具有自锁功能，使别组的抢答开关不起作用。 设置计分电路。每组在开始时预置成6分，抢答后主持人计分，答对一次加1分。(The design can accommodate a the Entrants digital intellectual Responder, each set answer in a key circuit has a first answer in the signal to identify and latch functions. Host to the system reset and sent the answer in instruction, participants answer in key, the group of the group light and display the answer in the group. At this point, the circuit has a self-locking function does not work in other groups to answer switch. Set Scoring circuit. Preset six points each at the beginning of the answer in scoring after the host, answer time, add 1 point.)
