摘要
以TMS320VC5509A作为硬件平台,采用SD卡作为外部掉电存储介质,介绍一种基于TMS320VC5509A的SD卡文件系统的实现方法。把TMS320VC5509A采集到的数据以标准文件的形式保存到SD卡中,通过读卡器在计算机上读取相关结果。该文件系统方案已经应用于工程声波仪(TMS320VC5509A作为仪器数据采集板核心处理器)中,实验结果表明该方案使得工程声波仪在数据测量中更加灵活,文件管理更加方便,具有较高的实用价值。
This paper introduces TMS320VC5509A as hardware platform,and adopts SD card as external storage medium power off,the way of realizing SD card file system based on TMS320VC5509A,data acquisited through TMS320VC5509A are preservated in SD card according to standard format,the relevant results can be accessed on computer through reader.The realized file system program have already applicated acoustic instrument engineering （using TMS320VC5509A as data acquisition board core processors）,experimental results show this program makes acoustic instrument measurement data more flexible,file management simple convenience,has high practical value.
