Abstract | Dynamic voltage scaling (DVS) which is an effective energy minimization technique has been well-studied in recent years. Yet the problem of selecting voltage levels for multiple voltage DVS systems remains an unresolved issue. In this paper, we present a novel technique for dealing with the problem of finding k operating voltages to minimize the energy consumption (voltage set-up problem). A new formulation of the voltage set-up problem is given to make our solution less dependent on the specific DVS scheme. Then it is solved optimally using dynamic programming in polynomial time. With almost the same time complexity we extend the proposed technique to explore the design space to determine the best number of voltage levels. It is confirmed from the experiments that the proposed voltage set-up solution reduces energy consumption by 19.2% on average over that of previous technique (Buss et al., 2003). |

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.
