摘　　要：针对光电跟踪测量系统高精度测量对高帧频、大靶面图像传感器图像数据超高速实时存储的需求,提出基于DDR模组阵列的超高速数字图像存储方案。该方案采用大容量DDR双列直插内存模组(DIMM)阵列作为存储介质,使用现场可编程门阵列(FPGA)实现DDR模组阵列控制器,在实验中实现数据率为1 000 Mb/s的超高速大容量数据实时存储,且其理论的最高数据存储速率可达1 828 Mb/s。To meet the demand of real-time image storage of high resolution high-speed image sensor in Opto-Electronic measuring system for the purpose of high accuracy, an image storage scheme based on DDR DIMM array technology was put forward. By applying the DDR DIMM memory as the storage medium and FPGA as the memory controller, a real time image storage at 1 000 Mb/s was accomplished in experiment, while the highest storage rate can achieve 1 828 Mb/s in theory.
