| Abstract | Due to the portability, low power consumption and robustness, flash memory is one of the popular storage devices for small electronic equipments like smart phones and PMPs (Portable multimedia players). However, it suffers from performance bottlenecks caused by asymmetric speed between read and write operations. A lot of previous researches focused on improving address mapping schemes in FTL (Flash Translation Layer) to reduce the number of write operations which are more expensive, but they rarely consider semantic factors like data file formats and detailed sequence of write operations. In this paper we suggest a new performance enhancement technique for flash memory, where a file format is reorganized to segregate read-only data and writable data. Since converting every standardized data format to a new one is unrealistic, we use static analysis and program translation--the transformed programs keep the writable data in the same block, rather than allowing it to be scattered over a larger number of blocks mixed with read-only data. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
