| Abstract: | 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 be increased obviously. |
