| Abstract | Nanophotonic is an emerging technology considered as one of the key solutions for future generation on-chip interconnects. Indeed, this technology provides high bandwidth for data transfers and can be a very interesting alternative to bypass the bottleneck induced by classical NoC. However, their implementation in fully integrated 3D circuits remains uncertain due to the high power consumption of on-chip lasers. However, if a specific bit error rate is targeted, digital processing can be added in the electrical domain to reduce the laser power and keep the same communication reliability. This paper addresses this problem and proposesto transmit encoded data on the optical interconnect, which allows for a reduction of the laser power consumption, thus increasing nanophotonics interconnects energy efficiency. The results presented in this paper show that using simple Hamming coder and decoder permits to reduce the laser power by nearly 50% without loss in communication data rate and with a negligible hardware overhead. |

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.
