基于alteraCPLD芯片的VHDL点阵滚动显示源代码

说明：  实现简单的硬件加法器、除法器，实现源码文中注释(Realize simple hardware adder and divider, realize source code)

实用Verilog编写的SVPWM程序，产生出SVPWM波形，可用于实现同步电机或者异步电机的空间矢量控制算法。(Practical Verilog of SVPWM written procedures, resulting in the SVPWM waveform can be used to implement the space vector control algorithm of the synchronous motor or induction motor.)

VHDL operators basics

基于FPGA实现蜂鸣器播放音乐的功能 使用芯片为EP2C8Q208C8N,使用普通蜂鸣器，由于频率不同可实现放歌功能，本例设计的是《友谊地久天长》，使用Verilog语言编程，本例子有工程文件、仿真、波形，经过测试可以使用。(Play music based on FPGA buzzer functions using chip EP2C8Q208C8N, using ordinary buzzer, since the frequency of different functions can be realized sing, in this case the design is " Auld Lang Syne" , using Verilog language programming, this project examples files, simulation, waveform, tested can be used.)
