数控分频器的设计数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法...

FPGA实验，实现了蜂鸣器发出不同的音调，利用按键，很好玩的-FPGA experiment, realized the buzzer sounded a different tone, the use of keys, it is fun

Service Manual LG TV LCD DISPLAY models 2011

此模块模拟alu（算术逻辑单元）和测试台，以验证其工作是否正确。

FPGA做机器人舵机控制系统，verilog(FPGA to do the robot servo control system, verilog)

本源码为Nios II的开发示例,主要演示Nios II的I2C总线设计。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。-The source code for the Nios II development of an example, the main demonstration Nios II I2C-bus design. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.

USB接口控制器参考设计VHDL代码,方便开发FPGA人员进行USB的开发，是一个不错的源码。-USB interface controller reference design VHDL code, facilitate the development of FPGA personnel USB development, is a good source.

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).

利用FPGA实现的脉宽测试技术,基于VHDL,测试误差为时钟周期-Use of FPGA technology to achieve the pulse-width test, based on VHDL, test error of clock cycles

用DE0开发板实现电话计费器，基本功能：可设置通话模式，能初始化话费余额，拨动开关可进入通话模式，并根据通话时间和相应通话模式扣除相应的费用。通话过程中能够通过开关切换显示通话时间和话费余额，并可暂停通话。压缩包里有详细的WORD文档的说明，包括波形仿真和DE0的引脚功能介绍。(Implemented by DE0 board telephone billing, basic function: to set the call mode, you can initiate credit balance, toggle switch into the talk mode, and deduct the cost of a call based on call time and the corresponding mode. Call talk time and can be displayed by switching credit balance, and mute. Compression bag has a detailed description of WORD documents, including the waveform simulation and DE0 pin function description.)

说明：  在MATLAB下自编实现快速傅里叶分析，(Fast fft own procedures, faster than the system call fft slowe)
