| Abstract | The increased demand for on-chip communication bandwidth as a result of the multi-core trend has made networks on-chip (NoCs) a compelling choice for the communication backbone in next-generation systems [3]. However, NoC designs have many power, area, and performance trade-offs in topology, buffer sizes, routing algorithms and flow control mechanisms---hence the study of new NoC designs can be very time-intensive. To address this challenge we propose DART, a fast and flexible FPGA-based NoC simulation architecture. Rather than laying the NoC out in hardware on the FPGA like previous approaches [8, 6], our design virtualizes the NoC by mapping its components to a generic NoC simulation engine, composed of a fully-connected collection of fundamental components (e.g., routers and flit queues). This approach has two main advantages: (i) since FPGA implementation is decoupled it can simulate any NoC; and (ii) any NoC can be mapped to the engine without resynthe-sizing it, which can take time for a large FPGA design. We demonstrate that an implementation of DART can achieve over 100x speedup relative to a cycle-based software simulator, while maintaining the same level of simulation accuracy. |

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.
