| Abstract | Predictability of multi-processor systems-on-chip communication is critical and needs to be addressed by providing the right mix of soft and hard real-time guarantees. To this end, state-of-the-art packet-switched networks-on-chip (NoC) provide different levels of quality-of-service (QoS) such as best effort (BE) and guaranteed throughput (GT). Unfortunately, GT resources have to be reserved for the worst-case, resulting in over-allocated resources. We introduce the SuperGT NoC, a packet-switched NoC that, besides BE and GT, supports a new SuperGT QoS. A SuperGT connection combines guaranteed and non guaranteed traffic while maintaining in-order packet delivery. Time-slots are allocated to provide guarantees and extra BE resources are claimed by injecting data during free slots. Simulation results demonstrate the advantages of SuperGT over GT. Synthesis results of the SuperGT virtual channel manager show that the SuperGT router is an inexpensive enhancement to state-of-the-art packet-switched 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.
