adc0809的fpga时序电路接口程序

标准RS422 Verilog源代码， 传输波特率可以修改， FPGA上可以工作(Standard RS422 verilog communication source code, buardrate can be updated and it is fully work in FPGA )

企业用verilog代码风格规范 本规范规定了IC设计项目开发过程中VerilogHDL源代码的编写总则、要求及模板文件。(Enterprises with verilog code style guide for the preparation of this specification General IC design project development process VerilogHDL source code, requirements and template files.)

这是基于Nios II的12864液晶点亮程序，包含汉字、字符等(This is a program which is based on Nios II ,its function is light the 12864 LCD that including Chinese characters, characters)

使用vhdl语言在altera公司的up3板上产生vga信号，里面有详细的解析和说明，是一个很好的教程。和上一个文件razzle差不多，但是产生的效果不一样。-use of the VHDL language ALTERA company"s board up3 have vga signal containing a detailed analysis and explanation is a good guide. And on a razzle almost document, but the effects are not the same.

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.)

无线通信FPGA设计Matlab Verilog代码(Wireless FPGA design Matlab Verilog code)

本文以FPGA为硬件平台，基于EDA工具QUARTUSⅡ为软件平台上对HDB3编/译码进行实现。由于在EDA的软件平台QUARTUSⅡ上不能处理双极性的信号，因此对HDB3码的编/译码的实现分为：软件部分和硬件部分。软件部分是基于QUARTUSⅡ的平台上对输入的码元进行编码和译码，通过系统仿真，验证了HDB3码的编译码的正确性；硬件部分采用CD74HC4052双四选一的数模选择器实现单极性到双极性的转换；采用AD790和SE5539实现双极性到单极性的转换。最后，通过仿真，验证了方案的正确性。
