数控分频的一个工程

这是FPGA的一个简单例程，LED键盘显示程序，非常时候大家入门学习-This is the FPGA, a simple routine, LED keyboard display program, very time we started to learn

基于fpga和xinlinx ise的小游戏的vhdl程序，希望对你有所帮助！-xinlinx and they simply based on the small game and ideally the VHDL process, and I hope to help you!

MIG IP控制DDR3读写测试，于MIG IP核用户接口时序较复杂，这里给出扩展接口模块用于进一步简化接口时序。(MIG IP controls DDR3 reading and writing tests, and the time sequence of MIG IP kernel user interface is more complex.)

这是我毕业设计做的一个SVPWM同步永磁交流电机的控制系统，里面除了一个SVPWM的驱动算法之外，还有一个步进电机的控制器，以及基于QUARTUS7.2的NIOS II控制核心，通过PC的串口可以控制同步永磁交流电机和步进电机进行精确的定位。该系统较复杂，运用的知识也比较多，在SVPWM算法，PID算法，步进电机控制方面，NIOS II的串口编程等都有值得参考的地方。最好使用QUARTUS7.2编译，目标芯片是选用EP1C6Q240-This is my graduation project SVPWM make a permanent magnet AC synchronous motor control system, which apart from a driver SVPWM algorithm, there is a stepper motor controller, as well as QUARTUS7.2 based on the NIOS II control core, through PC serial port can be controlled permanent magnet AC synchronous motor and stepper motor for accurate positioning. The system is more complicated, the use of more knowledge, in the SVPWM algorithm, PID algorithm, stepper motor control, NIOS II serial programming, such as places are worth considering. QUARTUS7.2 compile the best use of the target chip is optional EP1C6Q240
