A4_Oscilloscope_Top
数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

第七次课--视频图像DCT处理及水印嵌入
熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。
利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。
利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。
利用双线性插值方法实现对图像640×480到1024×768的放大操作。
完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format.
Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface.
With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA.
The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768.
Complete the VGA display interface design.)

counter
设计一个十进制计数器模块，输入端口包括 reset、up_enable 和 clk，输出端口为 count
和 bcd，当 reset 有效时（低电平），bcd 和 count 输出清零，当 up_enable 有效时（高电
平），计数模块开始计数（clk 脉冲数），bcd 为计数输出，当计数为 9 时，count 输出一
个脉冲（一个 clk周期的高电平，时间上与“bcd=9”时对齐）(Design of a decimal counter module, input port, including the reset up_enable clk, output port for the count and bcd, when reset is active (low), the bcd and count output cleared up_enable active (high), count module starts counting the (the CLK pulse number), the BCD count output when the count 9, the count output of the high level, the time of a pulse (a clk cycle with " bcd = 9" when aligned))
