基于ATR结构的嵌入式NAND Flash图像记录系统

摘要

The recording system used in aviation, requires a higher maintainability and reliability compared with ground system. The volume and dissipation also have strict limit. In order to solve the requests, embedded NAND Flash image recording system based on Austin Trumpbell Radio (ATR) reinforced structure is proposed. The system uses CPCIE 3U standard for design and is placed in the 1/2 ATR box, so the system has a higher maintainability and reliability. High-speed SRIO bus and NAND Flash recording arrays are used to achieve a high-speed real-time storage. The paper introduces the design of every card. The test results show the system run stably and reliably .The recording speed of the system is up to 912 MB/s and satisfies the recording requirement for high-resolution aviation CCD camera.%应用于航空的记录系统，要求具有比地面系统更高的可维护性和可靠性，体积和功耗也有严格的限制。针对这些要求，本文提出了基于ATR加固结构的嵌入式NAND Flash图像记录系统。系统采用CPCIE 3U规范设计，置于1/2 ATR机箱内，增强了系统的可靠性和可维护性。通过引入SRIO高速总线和NAND Flash存储阵列，解决了数据的高速实时记录。在此基础上，详细阐述了系统各板卡的设计。实验结果表明，该记录系统运行稳定可靠，记录速度达到912 MB/s，满足高分辨率航空CCD相机的记录要求。
