【摘要】：机载合成孔径雷达成像系统被广泛应用于救灾监测、地质绘测等民用领域和战场监视、军事侦察等军事领域。在飞机体积和载重能力都受限的情况下，需要采用高密度高速的存储系统实时存储海量数据。本文设计了一款以NAND Flash为存储介质的高密度高速存储板。板卡实现了记录、回放、导入、导出和简单文件管理功能。在软件上，移植MicroBlaze嵌入式微处理器作为主控制器，并设计了NAND Flash阵列控制器和PCIe控制器。NAND Flash阵列控制器集成了ECC校验和坏块管理功能，实现复位、编程、读取以及擦除等操作。PCIe控制器在PCIe集成端点硬核的基础上实现了与上位机之间的PIO和BMD两种数据传输方式以及中断功能。实验结果表明，本文所设计的高密度高速存储系统性能可靠，，可操作性高，具有很强的实用性。
[Abstract]:Airborne synthetic aperture radar imaging system is widely used in civil fields such as disaster relief monitoring, geological mapping and other military fields, such as battlefield surveillance, military reconnaissance and so on. In the case of limited aircraft volume and load capacity, it is necessary to use high density and high speed storage system to store massive data in real time. In this paper, a high density and high speed storage board with NAND Flash as storage medium is designed. The card realizes the functions of recording, playback, import, export and simple file management. In the software, the MicroBlaze embedded microprocessor is ported as the main controller, and the NAND Flash array controller and the PCIe controller. NAND Flash array controller are designed to integrate the ECC check sum bad block management function to realize reset and programming. PCIe controller realizes PIO and BMD data transmission mode and interrupt function with host computer on the basis of PCIe integrated endpoint hard core. The experimental results show that the high density and high speed storage system designed in this paper has reliable performance, high maneuverability and strong practicability.
