| Abstract | High-performance computing (HPC) systems demand aggressive scaling of memory and I/O to achieve multiple terabits/sec of bandwidth. Minimizing I/O cost, area and power are crucial to achieving a practically realizable system with such large bandwidth. To meet these needs, we developed a low-power dense 64-lane I/O system with per-port aggregate bandwidth up to 1Tb/s and 2.6pJ/bit power efficiency. We developed a high-density connector and cable, attached to the top side of the package that enables this high interconnect density. A lane-failover mechanism provides design robustness for fault-tolerance. To further optimize power efficiency, the lane data rate scales from 2 to 16Gb/s with non-linear power efficiency of 0.8 to 2.6pJ/bit, providing scalable aggregate bandwidth of 0.128 to 1Tb/s. Highly power scalable circuits such as CMOS clocking and reconfigurable current-mode (CM) or voltage-mode (VM) TX driver enable the 8× bandwidth and 3× power efficiency scalability with aggressive supply voltage scaling (0.6 to 1.08V). |

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.
