41_eth_ddr3_lcd
说明: “基于 ROM 的 LCD图片显示实验 ”中利用 FPGA 片上存储资源存储图片,并通过 LCD接口将图片显示到 LCD屏幕上。但是由于 FPGA 片上存储资源有限,只能存储分辨率较小的图片(In the experiment of LCD image display based on ROM, FPGA on-chip storage resources are used to store pictures, and the pictures are displayed on LCD screen through LCD interface. However, due to the limited on-chip memory resources of FPGA, it can only store images with smaller resolution)

第七次课--视频图像DCT处理及水印嵌入_2
说明: 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.)

说明: 该资料是用vhdl编写的按键消抖程序,按键消抖在使用按键的数字电路中非常重要,如果不对按键信号进行处理,有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序,文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试,并且在电路板上调试通过,效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)
