通过高级技术附加装置(ATA)存储接口扩展和文件系统算法研究,以TMS320DM642为实验平台,高效地实现了一种将DSP视频压缩码流实时存储为FAT32文件系统的大容量存储方法,解决了DSP系统在存储领域的兼容性等问题。
According to the analysis of file system and storage interface in Advanced Technology Attachment (ATA), a novel algorithm of FAT32 file system and AVI file format based on DSP is proposed, and is realized on experimental platform TMS320DM642. By using this system, the compatibility of video storage can he increased obviously.
