Design and Implementation of Log Structured FAT and ExFAT file Systems
2015Co-Authors: Keshava Munegowda, G T Raju, Veera ManinkAbstract:Abstract — The file allocation table (FAT) file system is supported in multiple Operating Systems (OS). Hence, FAT file system is universal exchange format for files/directories used in Solid State Drives (SSD) and Hard disk Drives (HDD). The Microsoft Corporation introduced the new file system called Extended FAT file system (ExFAT) to support larger size storage devices. The ExFAT file system is optimized to use with SSDs. But, Both FAT and ExFAT are not power fail safe. This means that the uncontrolled power loss or abrupt storage device removable from the computer system, during file system update, causes corruption of file system meta data and hence it leads to loss of data in storage device. This paper implements the Logging and Committing features to FAT and ExFAT file systems and ensures that the file system meta data is consistent across the abrupt power loss or device removal from the computer system

Methodologies for Geotagging in FAT and ExFAT file Systems for Smart Phones
International Journal of Computer Applications, 2014Co-Authors: Keshava Munegowda, G T Raju, Veeramanikandan RajuAbstract:ABSTRACT file allocation table (FAT)file system is the most common file system used in embedded devices such as smart phones, digital cameras, smart TVs, tablets, etc. Typically these embedded devices use Solid State Drives (SSD) as storage devices. The ExFAT file system is future file system for embedded devices and it is optimal for SSDs. This paper discourses the methodologies for Geotagging as a file system metadata instead of file data in FAT and ExFAT file systems. The designed methodologies of this paper adheresthe compatibility with the FAT file system specification and existing ExFAT file system implementations. Keywords Cluster, Contiguous, ExFAT, EXIF, FAT, file system, Flash memories, GPS, MMC, Multimedia, Micro SD, NAND, NOR, SSD,Storage, Video, XMP. 1. INTRODUCTION The Multimedia Cards (MMC) [1]/ Secure Digital (SD) [2] / Micro SD cards are composed of NOR and/or NAND flash memories [3]. The NOR and NAND flash memories are also called as “Solid State Drives”. The Flash memories are default choice of any embedded device as they are low-priced, smaller size and higher storage capacity.The FAT [4] file system is the widely adopted file system in SSDs. The multi-media applications such as video imaging, audio/video playback and recording uses FAT file system for storing and retrieving the data of the multimedia files. The first version of FAT file system was FAT12 by Microsoft Corporation, later it was extended as FAT16 and further as FAT32 to support higher storage capacity. The FAT file system was initially developed to use on floppy disks and Hard Disk Drive (HDD) s. Since most of the operating systems of Personal Computer (PC) s such as Windows, Linux, Mac OS, etc. implement the FAT file system, this file system has become a default and world-wide compatible storage format for embedded devices. Usually the device with the implementation of FAT is recognized as removable storage media in a PC. Even though FAT file system does not define flash management techniques such as Wear-Levelling and Bad Block management [4], the embedded devices implements this file system along with the dedicated flash block management algorithms. In FAT file system, the storage device is represented as group of linear clusters. A cluster is basic unit of data storage in FAT file system and it is a group of blocks or sectors of storage device. In FAT file system, the file or directory is a linked list of the clusters. The file allocation table stores the status of all available clusters of the device; Status of a cluster can be either allocated as part of file/directory data or free or reserved. An every entry of file allocation table indicates the status of corresponding cluster. The FAT file system specification limits the maximum supported storage size to 32 GB. But, the maximum size supported by FAT32 implementation is 128 GB. But, today the flash storage cards of more than 32 GB are available in market. The ExFAT [5] [6] file system is developed, by Microsoft Corporation, as successor of FAT32 file system. This file system is optimally designed to support large size flash storage cards with higher read and write performance. The maximum storage size supported by ExFAT file system in 128 peta bytes (PB). Global PositioningSystem (GPS) based positioning [7][8]is the positioning technique commonly used inSmartphones. Most of Smartphone contains the GPS receiver which continuously receives the signals from the satellites. These satellite signals contain the exacttime of the message sent, and the location information. The GPS receiver usesthe received signals of four or more satellites to determine the current position based on trilateration.Many smart phones uses the multiple sensors improve the accuracy of the GPS position [9]. In Android based mobile phones, Location Manger [10] can be used for the Geotagging of multimedia files. The eXtensible Metadata Platform (XMP) [11] and Exchangeable image file format (EXIF) [12] are the formats used to store the geographical coordinates and other related information in multimedia and Portable Document Format (PDF) files. In both XMP and EXIF formats, the Geographical data is always placed as multimedia file data. Due to this, file need to be opened and read operation is required to retrieve the geographical location of the file. This paper designs the techniques to place the geographical data of the file as attribute of the file instead of user data of the file. In FAT and ExFAT file systems, the attribute of the file contains the file name, size in bytes, date and time of creation and last write. The attribute of the file is referred as Meta data of the file. This paper includes the geographical data to the attribute of the file/directory by following methodologies. i) Geotagging with Reserved Sectors of FAT and ExFAT file systems. ii) Geotagging with Reserved Clusters of FAT file systems. The files created/updated with above techniques adheres the compatibility with the existing FAT and ExFAT file system implementations and specifications. This means, files created with Geographical data as attributes are accessible for read and write operations in other FAT and ExFAT file system implementations without Geotagging facility. The Geotagging methodologies described in this paper stores the geographical

ISCAS - A 65 nm uneven-dual-core SoC based platform for multi-device collaborative computing
2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014Co-Authors: Wenping Zhu, Leibo Liu, Shouyi Yin, Dong Yuan, Shaojun Wei, Eugene Y. Tang, Jiqiang Song, Peng JinzhanAbstract:Multiple mobile device-based collaborative computing emerges with the rapid proliferation of various smart mobile devices such as smartphones and tablets, which provide always-on connectivity, information and communication. However, due to severe resource poverty and poor network connectivity, lots of traditional embedded electronic devices with attracting features cannot be incorporated into this computing paradigm conveniently. In this paper, an uneven-dual-core SoC, which integrates a CPU core and a MCU core on a single chip with multiple operating system support, is proposed to realize loosely-coupled multiple heterogeneous device collaboration. A network file system, MRFS (Multi-client Raindrop file System), and FAT-X (file allocation table eXtension) are also proposed to provide client-centric cross-device data consistency and virtual file access respectively. Comprehensive mobile services are enabled by offloading appropriate tasks from existing smart mobile devices to involved traditional embedded devices. The SoC is implemented onto a 16.65 mm 2 silicon with 65 nm CMOS technology. This paper also presents three typical applications to illustrate the universality and huge potential for innovative usage model of the proposed system.
