参数化 FFT

DDS中的正余弦生成，初始相位相差90度，可自行改变输出频率(Cosine generation of DDS, the initial phase difference of 90 degrees, the output frequency can be changed on their own)

用FPGA实现 VGA显示的图像显示控制器设计 用VHDL实现 硬件实现是屏幕上面出现彩色条纹(VGA display with FPGA image display controller design Using VHDL hardware implementation is colored stripes appear above the screen)

用Verilog实现汉明码编码，经测试可正确使用，代码简洁(Verilog with Hamming code encoding, the test can be used correctly, the code is simple)

交通灯电路，南北方向和东西方向分别按绿灯、黄灯、左拐灯、黄灯、红灯的顺序两灭，数码管显示相应的灯亮的时间的倒计时。已通过编译和仿真。-Traffic light circuit, north-south direction and east-west direction respectively green, yellow light, left light, yellow light, red light destroy the order of two, a digital LED display lights the corresponding period of the countdown. Has passed the compilation and simulation.

Laplace可以应用于图像的锐化，根据其原理，对于Laplace后的图像同样可以进行边缘检测。(Laplace can be applied to image sharpening. According to its principle, edge detection can also be performed for images after Laplace.)

高精度小数除法器设计与实现。 在FPGA开发板上实现小数除法器，输入输出信号N_in [15:0], D_in[15:0]，N_in[15:0]小于D_in，即被除数小于除数，输出商Q_out[15:0]中Q[15]一定为0，Q[14:0]为商的小数部分。输入和计算结果通过VGA显示。(Precision fractional divider design and implementation. In the FPGA development board fractional divider, input and output signals N_in [15: 0], D_in [15: 0], N_in [15: 0] less than D_in, ie the dividend is less than the divisor, quotient output Q_out [15: 0] in Q [15] necessarily 0, Q [14: 0] for the business of the fractional part. Input and calculation results display by VGA.)
