| Abstract | As mobile phones become increasingly multifunctional, the number and size of applications installed in phones are rapidly increasing. Consequently, mobile phones require more hardware resources such as NOR/NAND flash memory and DRAM, and their production cost is accordingly becoming higher. One candidate solution to reduce production cost is demand paging using MMU. However, demand paging causes unpredictably long page fault latency, and as such mobile phone manufacturers are reluctant to deploy this scheme. In this paper, we present a method that reduces the long latency of page faults by performing page fault handling in a parallelized manner, considering the characteristics of NAND-Type flash memory. We also discuss how to modify the existing page cache replacement policies so that they can exploit the benefits of the parallelized page fault handler. Experimental results show that the parallelized page fault handler improves the worst case latency of page faults significantly, by up to roughly 20%, and that the modified page cache replacement policies improve both the average and worst instruction fetch time. |

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.
