| Abstract | In this paper, we address the problem of scheduling operations into control steps with dual threshold voltage (dual-Vth) technique under timing and resource constraints. We present a min-cut based algorithm for leakage power optimization. The proposed algorithm first initializes all the operations to high-Vth, then iteratively shorten the critical path delay by reassigning the set of operations covering all the critical paths to low-Vth until the timing constraints are met. A modified force-directed scheduling is implemented to schedule operations and to adjust threshold voltage assignments with consideration of resource constraints. During this procedure, mobility overlap graph (MOG) is constructed based on the mobilities of high-Vth operations. To guarantee the resource constraints are satisfied, operations' threshold voltages are adjusted by computing the min-cut of MOG. Experimental results show that our method performs better both in running time and leakage power reduction compared with MWIS_heuristic [3]. |

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.
