摘　　要：为了满足视频处理中数据的高速读写,使用FPGA定制了一种SDRAM控制器,此控制器能够通过采用切换bank操作、自动预冲、集中刷新等组合操作实现任意突发长度的数据读写,满足了对连续视频数据的存储要求。In order to meet the high speed read/write in vedio processing, a SDRAM controller designed based on FPGA is used. The controller is able to realize the data reading/writing of any burst length through combined operations such as switching bank, auto precharging, concentrated refreshing, so that it can be used for the storage of continuous video data.
