Fast accessing of geographic remote sense image (GRSI) in geographic information system has been a different problem in the region of remote sense information processing for years. This paper proposes a efficient way called IBSA (Image blocking storage approach) for GRSI based on the flash storage technology which is a hot research topic in data storage field. IBSA exploits a blocking approach which...
Wear-leveling algorithm is required in most flash memory controllers to prolong the lifetime of flash memory by distributing the erase operations evenly across the whole flash memory. This paper proposes a group based wear-leveling algorithm which can dramatically reduce the RAM space required by wear-leveling algorithm while maintaining the wear-leveling performance. We adopt random wear-leveling...
the storage for mass data in geo-information system always restricts its development. Solid State storage is an efficient storage method based on semiconductor device, with superior performance and flexible management. Aiming at meeting the storage requirement of remote sensing image and making good use of solid state storage's advantage, the paper studies storage management mode based on Flash parallel...
Object Based Storage Device (OSD) takes object as the purpose of storage and management, OSD can be regarded as the convergence of two technologies: files and blocks. The most distinct difference between OSD and traditional storage device is the storage interface, and different storage mediums also affect the performance notability. NAND flash based solid state storage has become the mainstream of...
