| Abstract | Networks-on-chip (NoCs) are becoming increasingly important in general-purpose and application-specific multi-core designs. Although uniform router configurations are appropriate for general-purpose NoCs, router configurations for application-specific NoCs can be non-uniformly optimized to application-specific traffic characteristics. In this paper, we specifically consider the problem of virtual channel (VC) allocation in application-specific NoCs. Prior solutions to this problem have been average-rate driven. However, average-rate models are poor representations of real application traffic, and can lead to designs that are poorly matched to the application. We propose an alternate trace-driven paradigm in which configuration of NoCs is driven by application traces. We propose two simple greedy trace-driven VC allocation schemes. Compared to uniform allocation, we observe up to 51% reduction in the number of VCs under a given average packet latency constraint, or up to 74% reduction in average packet latency with same number of VCs. Our results suggest that average-rate driven methods cannot effectively select appropriate links for VC allocation because they fail to consider the impact of traffic bursts. As a case study, we compare our proposed approach with an existing average-rate driven method [9] and observe up to 35% reduction in the number of VCs for a given target latency. |

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.
