| Abstract | High performance and computational capability in the current generation processors are made possible by small feature sizes and high device density. To maintain the current drive strength and control the power dissipation in these processors, simultaneous scaling down of supply and threshold voltages is performed. High device density and low threshold voltages result in an increase in the leakage current dissipation. Large on chip caches are integrated onto the current generation processors which are becoming a major contributor to total leakage power. The proposed static power reduction technique, GALEOR (GAted LEakage TransistOR), reduces the leakage current flowing through the circuits. In the proposed leakage power technique, two gated leakage transistors are inserted between NMOS and PMOS circuitry of the existing circuit such that gates of the extra inserted transistors are connected to their respective drain regions. GALEOR technique was tested on standard cell gates and memory elements. Area overhead is minimized by eliminating the use of control logic to switch between the active and standby states. Performance overhead is increased due to the reduced output voltage swing. |

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.
