数字频率计~ VHDL 实现 可以实现频率的测量和现实的功能 8位

本代码实现了全加器的功能，可供初学者学习-This code implements a full adder functions, for beginners to learn

3-8译码器，可以讲三位二进制输入转换为8中取1的输出信号(3-8 decoder, you can talk about the three binary input is converted to 8 of the output signal from 1)

基于sopc的lcd时钟，开发工具为nios ii和quartus ii9.0(Based on sopc the lcd clock, development tools for the nios ii and quartus ii9.0)

实现dsp与fpga的emif的verilog异步实现，可实现异步读写以及相应功能模块控制，文件中包含仿真后的波形图形以及仿真测试程序，运行环境quartus ii11.0，仿真环境mmodelsim se 6.5d(Achieve dsp and fpga verilog asynchronous implementation of the emif, enabling asynchronous reading and writing as well as the corresponding function module control, the document contains graphics, and after the simulation waveform simulation testing procedures, operating environment quartus ii11.0, simulation environment mmodelsim se 6.5d)

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).

VHDL 乘法器 源代码，很好的VHDL 入门学习例程序-Multiplier VHDL source code, a good learning example VHDL entry procedures

用case 语句描述的4 选1 Mux 源码程序，好用(-4 with a case statement described 1 Mux source program, easy to use)

基于单片机的DDS信号发生器，具有DDS思想的单片机编程。。。(Sunplus based DDS signal generator with DDS thinking microcontrollers. . .)

基于CPLD的实现控制8x8点阵动态显示心型图案的程序，使用VHDL语言，通过调节分频系数可以实现点阵的变换速度，通过改变不同的状态可以让点阵显示不同的图案。

VHDL的重要PPT资料,对初学者非常有益处-VHDL important PPT information is very useful for beginners
