说明：  基于EasyFPGA030的四位数字密码锁。(Based on the four-digit lock EasyFPGA030.)

在FPGA内部实现数据大小排序是一件非常困难的事情，本例中以流水线方式实现16个数据的排序！

运用vhdl硬件描述语言在quartus II开发环境下独立设计与实现了基于精简指令集的五级流水线CPU的设计与实现。该流水CPU包括：取指模块，译码模块，执行模块，访存模块，写回模块，寄存器组模块，控制相关检测模块，Forwarding模块。该CPU在TEC-CA实验平台上运行，并且通过Debugcontroller软件进行单步调试，实验表明，该流水线CPU消除了控制相关、数据相关和结构相关。(Using vhdl hardware description language development environment under quartus II design and implementation of an independent design and implementation of a five-stage pipeline RISC-based CPU' s. The water CPU include: fetch module, decoding module, execution modules, memory access module, the write-back module, the register set of modules, control relevant to the detection module, Forwarding module. The CPU in the TEC-CA experimental platforms, and single-step debugging through Debugcontroller software, experiments show that the pipelined CPU eliminates the control-related, data-related and structurally related.)

说明：  利用Matlab/simulink实现电力仿真，其中单相逆变可用于多电平变流器的基础使用，本案例提供了不同调制手段实现逆变的模型(Matlab / Simulink is used to realize power simulation, in which single-phase inverter can be used as the basis of multi-level converter. This case provides the inverter model with different modulation means)

基于FPGA设计的经典打砖块小游戏。游戏简单易玩。(FPGA design based on the classic Arkanoid game. Game easy to play.)

应用布莱克曼窗实现FIR滤波器，并绘制相应波形图案(Application Blackman window FIR filter, and draw the corresponding waveform pattern)

说明：  基于FIR设计的100阶数字滤波器，选择的矩形窗(100 - order digital filter based on FIR)
