VHDL_ 两个电路计数上 / 下液晶显示语言 VHDL (海 mạch đếm lên/xuống hiển 施耐液晶 bằng ngôn ngữ VHDL)

这是我从网上找到的用vhdl语言写的sdram控制器的代码。我的邮箱：wleechina@163.com-This is what I found online vhdl language used to write the sdram controller code. My mail : wleechina@163.com

说明：  用verilog编辑的中值滤波器！语言旁表有注释方便理解！(Using Verilog editor median filter! Language beside the table annotated to facilitate understanding!)

基于avgt开发板的jesd204b源代码，需要安装Quartus软件(Avgt development board based on the jesd204b source code)

在接收信号的数字化、软化的实现中,数字下变频起着重要的作用。本文首先介绍了数字下 变频的组成结构,然后详细分析了数字下变频的工作原理,描述了在实现数字下变频时,设计方案所 采用的高效滤波器———CIC 滤波器和多相抽取滤波器的结构和原理。最后,用通过Simulink 对数字 下变频的性能进行了仿真。在仿真的基础上使用Insight 公司的FPGA 开发系统,用测试电路实测了 数字下变频的性(In the receiving digital signal, softening the realization, the digital down-conversion plays an important role. This article first introduced the digital down conversion of the composition, and then a detailed analysis of digital down conversion of the working principle described in the realization of digital down conversion, the design used in high-performance filters--- CIC filters and multi-phase extraction filter structure and principle. Finally, with the adoption of Simulink for digital down-conversion performance of the simulation. In the simulation based on the use of Insight s FPGA development system is measured using the test circuit of the digital down-conversion of)

verilog 代码. 经验证成功,可以作为标准单元库,为FPGA设计者使用.-Verilog code. Certified success, as a standard cell library for the use of FPGA designers.

这是执行高速的代码通用异步收发器代码是用VHDL写的语言.UART是一种在传输端进行并行输入和串行输出，在接收端进行串行输入和并行输出的算法。

用blockram实现移位寄存器，开发语言为verilog hdl(Shift register with blockram achieve the development language for the verilog hdl)

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 )

verilog支持noise噪声的端口port, 可以用于仿真运行. 评估噪声影响 Verilog port that supports noise and can be used for simulation run. Evaluate noise effects

本文件包括整个基于QuartusII实现的抢答器模块，其下包括各个分模块，实现效果较不错。
