altera DE2 实验板专用 CCD驱动-altera DE2 board dedicated CCD driver

altera 公司的15IP源码 亲自测试还不错 有DIV, CONTER-ALTERA the 15IP source personally tests are also good DIV, CONTER

主要完成数字电视前端信号处理和缓冲作用的verilog源代码，可以直接使用 -the major digital TV front-end signal processing and buffer the Verilog source code can be used directly

针对兆瓦级风电并网逆变器主电路研制中存在的并联扩容、开关频率较低和LCL滤波器难以优化设计等问题，提出了采用交流侧串接电感再进行并联的均流方案，采用载波移相技术提高变流器的等效开关频率，提出了LCL滤波器的设计原则，并给出了上述设计的理论依据和实现方法。通过对2兆瓦风电变流器主电路的仿真验证了上述技术方案。(MW-class wind power for grid-inverter main circuit of the parallel development of existing capacity, a lower switching frequency and LCL filter design difficult to optimize the problem, a series inductor AC side in parallel are further flow program, the use of carrier phase-shifting technology to enhance the equivalent converter switching frequency, a LCL filter design principles, and gives the above-mentioned theoretical basis for the design and implementation. 2 MW of wind power converter main circuit simulation program to verify the above-mentioned technology.)

sd_sdram_lcd 是读取SD卡中的数据，然后通过LCD显示(It is to read the data in SD card and display it by LCD)

实现QPSK系统的调制解调仿真，基带成形滤波器采用升余弦滚降滤波器，将仿真的误码率与理论误码率作了比较(Implement QPSK modulation and demodulation simulation system, the baseband shaping filter using Raised Cosine filter will BER simulation were compared with the theoretical BER)

自己做的数码管显示的时钟 一个非常简单的FPGA时钟 用累加做的(To do their own digital display clock of the FPGA clock is a very simple to do with the cumulative)

本代码来自老师指导，自己编写，可以修改交通灯的时间

本例为电子琴VHDL程序原代码,电子琴,可实现基本功能-In this case the procedures for organ VHDL source code, organ, can realize the basic functions of
