【摘要】 提出一种基于页结构的专用读写控制器解决方案,将DVI接口的数字视频信号在SDRAM上进行连续或跳跃式快速页读写,并在FPGA上实现,解决了高速视频重组效率低的问题,实现了超大画幅图像的帧缓存和数据任意组包,可运用于LED全彩屏、组合液晶屏的控制系统中。更多还原

【Abstract】 A specific reading or writing(R/W)controller based on page-structure is proposed,which can proceed fast,consecutive or interleaving R/W operations from DVI on Synchronous Dynamic Random Access Memory(SDRAM).The design is built on FP- GA to improve the efficiency of digital video flow re-combination,and accomplishes large-scale frame’s buffer and random re- combination.This design can be used in the controlling system of full-color LED display and combined liquid crystal display.更多还原
