VHDL实现ALU的源代码，并且提供了一个详细的testbench！

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

文章运用分级抽取和多相滤波的方法改进传统CIC滤波器的结构,降低了系统工作频率,运用幅度改进函数(ACF)和外加级联余弦预滤波器的技术改进了滤波器频率响应,提出了一种高效的算法结构,改善了通带损耗,增大了阻带衰减,对CIC滤波器的实际应用和深入研究有着现实意义。 (Article the use of hierarchical multi-phase extraction and filtering methods to improve the structure of the traditional CIC filter, reducing the system operating frequency, the use of margin to improve the function (ACF) and the cosine cascade plus pre-filter technology to improve the filter frequency response, the an efficient algorithm to improve the pass-band loss, increases the stopband attenuation of the CIC filter in practical applications and in-depth study has practical significance.)

eda技术与vhdl课件,很经典的学习课件-VHDL EDA technology and courseware, it is a classic learning courseware

中值滤波实现。选择在Vivado软件上采用Verilog语言来编写中值滤波算法，搭建出完整的数据处理系统架构，通过仿真和验证来判断数据的处理效果，并在实际的设计过程中根据出现的问题提出解决方案。(Median filter implementation. The author chose Verilog language to write the median filter algorithm in Vivado software, built a complete data processing system architecture, judged the data processing effect through simulation and verification, and proposed a solution according to the problems in the actual design process.)
