AHB总线相关协议代码

poor scope is a vhdl implimentation pic micro controller

用verilog语言写的简单的键盘扫描代码，适合初学者，用alter的软件编写的程序代码。(Using verilog language to write simple keyboard scan code, suitable for beginners, with alter software program written code.)

浮点数运算的FPGA实现，包括仿真文件。(FPGA realization of floating-point operations, including the simulation file)

说明：  经过验证的经典实例，完全正确的。适合于入门新手的实例，仅供交流使用。(fpga exampe)

DDR2控制器设计原码,可以在FPGA上测试通过,并对外部的ddr memory进行读写访问.(DDR2 controller design of the original code, can be tested through the FPGA, and external ddr memory read and write access.)

VHDL Design of BCD to 7-segment decoder using PROM

基于Verilog代码的16点FFT算法，串行输入，quartusII中运行成功过。

说明：  串口！ 这是一个使用的通信程序 ， 非常好用。(serial port Serial port! This is a communication program used, very useful.)

说明：  在FPGA板卡上面，通过单个按键实现串口的发送功能，带仿真需要自行修改一下工程配置(On the FPGA board, the sending function of the serial port is realized by a single key, and the engineering configuration needs to be modified by the simulation)

该模块依据输入的温度，来自动调整PWM输出的占空比，从而进行CPU散热风扇的智能调速，温度需要上层软件往该模块中下发。
