| 中文摘要 | 介绍了一种基于FPGA内置NiosⅡ软核处理器的实时数据存储系统,存储介质采用CompactFlash存储卡,用于嵌入式移动测试系统的数据存储。在设计并实现硬件的基础上,针对现有FAT32链式操作复杂、反复寻址计算开销大的缺点,本文提出了将现有FAT32文件系统进行简化从而提高数据存储效率的方法,并用软件成功实现相应操作。; The design of real-time data storage system based on NiosⅡ soft-core CPU which embedded in FPGA is discussed firstly. The storage media is CompactFlash card, which is popular in industry measurement system. The system is used for data storage of embedded mobile measurement. The existing FAT32 file-system’s FAT chain operations are more complex and have more additional addressing. So an improvement of the old FAT32 is proposed, which simplifies the old one, and data storage’s efficiency is enhanced accordingly. At last, the corresponding software is successfully accomplished by C language. |
