摘　　要：在简要介绍SDRAM特点和基本操作原理的基础上,提出了一种基于FPGA的SDRAM控制器的设计方法,用Verilog硬件语言加以实现。分析了各模块的具体设计方案及整体设计的实现过程,最终实现将图像数据存入SDRAM,再通过SDRAM完成数据的读取,送入VGA进行显示,在输出显示屏上看到彩色图像则表明控制器的功能得以实现。The paper briefly introduces the characteristics of SDRAM and the basic operation principle, then puts forward a design method of SDRAM controller based on FPGA. The controller was achieved by the language of Verilog. The paper analyses the overall design and the specific realization of the design scheme of each module. Finally, the image data should be stored in SDRAM, and then the reading control through SDRAM should be achieved, which sent the data to display on the VGA screen. When the colorful picture was displayed on the screen, it means the function of the SDRAM controller was achieved.
