官方的RS232例程详细Altera非常实用

说明：  基于fpga的verilog实现ad及uart，并进行仿真验证(Verilog based on FPGA implements AD and uart, and carries out simulation verification)

主要完成数字电视前端信号处理和缓冲作用的verilog源代码，可以直接使用 -the major digital TV front-end signal processing and buffer the Verilog source code can be used directly

these is about code for dlx processor

用于FPGA的学习，大家值得借鉴，可以好好学习一下(this is for fpga and you can use this.)

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：  FPGA 读写 SRAM 存储块，verilog代码(Read and write SRAM memory block and Verilog code in FPGA)
