一种基于图像旋转显示的DDR2高效存储方法
An Efficient Storage Method of DDR2 Based on Image Rotation Display
摘要
Abstract
Image rotation is a common digital image processing technology which is widely applied in various fields. In image system, DDR2 is always used as the display memory. Image display system scans to refresh images usually from left to right and from top to bot-tom,then saving image data in the same order,but for image rotation display of maximum resolution,this general storage method can’ t meet the requirement of DDR2 bandwidth for system. In order to solve this problem,the high-effective storage method must be used. On the basis of the principle of image rotation display,contrasting the general storage method,the block storage method and efficiency of it is discussed. At last,FPGA verification is made in combination of project. The result indicates this block storage method increases bandwidth utilization of DDR2,which can meet the requirement of rotation display,and solves the problem which general storage method can’t meet maximum resolution image rotation display.关键词
