| Abstract | Collective communication support which has been playing a major role in network on chips (NoCs) is used for image processing, multimedia and other signal processing applications. Application Specific NoC utilizes multicasting (MC) and other services like reduction and scattering for parallel data processing. The proposed architecture introduces a new network model, wherein few extra network nodes named QaMC (Quality of Service Aware Multicast) routers have to be added to improve multicasting by providing a direct link to each individual router of the MC groups. It utilizes the concept of application mapping for the formation of MC groups. It also provides a circuit switched model of communication for unicasting through these direct links along with the normal unicasting without the usage of extra buffers. The direct link communication can also be utilized for Guaranteed Services (GSs), which is an added advantage. The proposed architecture along with QaMC routing algorithm enables efficient multicasting as well as guaranteed services in application specific NoCs. An efficient routing algorithm has also been proposed for the convenient flow of multicast packets as well as providing GS. The area overhead for the complete 4×4 mesh network obtained is of about 4.2 % which is comparably negligible and the concept can also be extended to 3D NoCs. |

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.
