H.264 VHDL Encoder

基于FPGA的PCI9054 LOCALBUS总线接口(PCI9054 interface program based on FPGA)

LDPC的短码，码长为40速率为0.5的LDPC码的设计，用的是QC矩阵，压缩文件为原码部分，工程太大传不上去。(LDPC short code, a code length of 40 rate of 0.5 LDPC code design, using a QC matrix, the compressed file is part of the original code, do not pass up the works too.)

nios大神进阶，一本非常好的FPGA书籍，从RTL到eclips(nios tech.a very good book learning FPGA tech.)

资源描述用verilog语言编写的曼切斯特编码和CRC校验程序，程序已经过验证，对此感兴趣的可以下载看看，非常好用。

offset_cancellation code for matlab to hdl

这是实现一个关于dmbt 3780点的fft 的算法的verilog code，该代码已经完成了硬件验证，为了捞点分，我把箱底的东东拿出来给大家分享了，希望对正在做这方面的同志提供一点帮助，唉

rmii 以太网接口时序源代码，值得开发借鉴的哦(verilog hdl)

从FPGA输出到HDMI Tx的verilog 模块。实现完整HDMI图像输出功能。(FPGA output to HDMI Tx module in verilog)

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.)

多相滤波系统的设计与实现，有MATLAB仿真程序，有sysgen的系统仿真，还有VHDL代码，其中还有FIR的系数参数等等(Polyphase filter system, the design and implementation includes a MATLAB simulation program, sysgen system simulation, and VHDL code, including FIR coefficient parameters, and so on )
