[File Format] designforvideobasedonSDRAM DL : 0: 在信息处理中，特别是实时视频图像处理中，通常都要对实现视频图像进行处理，而这首先必须设计大容量的存储器，同步动态随机存储器SDRAM虽然有价格低廉、容量大等优点，但因SDRAM的控制结构复杂，常用的方法是设计SDRAM通用控制器，这使得很多人不得不放弃使用SDRAM而使用价格昂贵的SRAM。为此，笔者在研究有关文献的基础上，根据具体情况提出一种独特的方法，实现了对SDRAM的控制，并通过利用FPGA控制数据存取的顺序来实现对数字视频图像的旋转，截取、平移等实时处理。-In information processing, especially real-time video image processing usually have to deal with video images, which must first be designed large-capacity memory, synchronous dynamic random access memory SDRAM Although there are low cost, large capacity, etc., but SDRAM control structure of the complex, commonly used method is to design generic SDRAM controller, which makes a lot of people had to abandon the use of SDRAM and the use of expensive SRAM. To this end, the authors examine the literature based on the specific situation in a unique way to realize the control of SDRAM, and control data through the use of FPGA to realize the order of access to digital video image rotation, interception, translation, such as real-time processing.
