摘　　要：为了提升红外热像仪图像处理系统中数据处理模块访问DDR存储器的带宽效率与系统可靠性,采用Xilinx Kintex-7系列FPGA设计了一种基于AXI4总线的DDR存储器访问方案,实现了AXI4总线的用户接口设计,完成了对DDR存储器的多端口实时访问控制需求。测试结果证明了设计的可行性,接口符合AXI4总线协议规定,使红外图像处理系统中数据模块对DDR的读写带宽与效率达到一个较高的水平。In order to improve the bandwidth efficiency and system reliability of the data processing module accessing the DDR memory in the image processing system of the infrared thermal imager,a DDR memory access scheme based on AXI4 bus is designed using Xilinx Kintex-7 series FPGA.The user interface design of AXI4 bus is realized,and the requirements for real-time access control of multiple ports of DDR memory are completed.The test results prove that the design is feasible,and the interface conforms to AXI4 bus protocol,so that the read/write bandwidth and efficiency of the data module in the infrared image processing system for DDR can reach a higher level.
