| 摘 要： | UBIFS文件系统中由UBI子系统实现磨损均衡管理,但研究发现UBI现有的磨损均衡策略存在着很大的局限性.提出了一种基于逻辑块温度和物理块年龄的新的磨损均衡算法,称为LTPA(leb temperature peb age)算法.该算法实现高温逻辑块与青年物理块,低温逻辑块与老年物理块之间的映射.通过局部操作时间的方法...

| Abstract: | UBI subsystem is achieving the management of the wear leveling in the UBIFS file system,but the study found that the wear of the existing equilibrium strategy UBI there are significant limitations.This paper propose a new algorithm which is based on the temperature of physical block and the age of the logic block,that is called LTPA(leb temperature peb age) algorithm.The algorithm maps the hot logical block to the young physical block,and the temperature of the cold logical block is mapped to an old physica... |
