摘要:
针对CDMA 6025手机研发平台设计了一种flash 文件系统, 其结构主要由driver层、core fun ct ion 层、target function 层、m anage function层和ffs task 层5 部分组成, 利用消息收发机制实现不同任务之间的数据交换和共享. 文件系统的设计主要包括目录结构、文件结构的设计和对象的删除、更名和修改, 同时通过查询b lock中的信息进行了F lash 寿命均衡设计. 目前在此基础上已经成功进行了系列CDMA 手机的研发, 该文件系统得到了很好的应用.
Abstract:
A k ind o f em bedded flash file system ( ffs) is designed to handset R&D platfo rm of CDMA 6025. Th is ffs h-i e rarchy is m ade up o f five parts such as dr iver, core function, ta rget function, m anage function and ffs task. Us ing messag e rece iv eing and d ispa tch ing m echan ism data ex chang ing and da ta shar ing is achieved in d ifferen t tasks. This designs inc ludes m ostly designs o f d irec to ry structure and file struc ture, de le ting, renam ing and am end ing of a object and ba-l ance design o f flash life by inqu iring the in fo rm ation o f b lo ck. In practice th is ffs is app ly ing effective ly, and based on it a ser ies o f CDMA mob ile phones are manufac tured.
