摘要
TFFS文件系统为各种FLASH存储器提供块设备接口,是M-System公司为Vxworks操作系统定制实现的。原先的TFFS的格式化在FTL层是按照FLASH的块进行格式化,由于FLASH的块数比较多,故格式化的时间比较长;快速格式化的原理是按照FLASH的片,使用整片擦除函数,提高FTL格式化的速度。测试结果表明,该方法和传统方法相比能大大提高FLASH格式化的速度。
TFFS（Ture Flash File System） provides device interface for all kinds of flash memory,which is customized for Vxworks operating by M-system company.Traditional TFFS formatting is formatted in accordance with FLASH blocks in FTL（Flash Translation Layer）.More formatting time is spent,because of numerous FLASH blocks.While the principle of fast formatting is according to flash chip,full-chip erasing function is used to improve the speed of FTL format.The experiment results show that this new method can improve the format speed distinctly.
