| Abstract | On-chip interconnection network is a crucial design component in high-performance System-on-Chips (SoCs). Many of previous works have focused on the automation of its topology design, since the topology largely determines its overall performance. For this purpose, they mostly require a switch library which includes all possible switch configurations (e.g. the number of in/output ports and data width) with their implementation costs such as delay, area, and power. More precisely, they characterize the switches by synthesizing them with a common design objective (e.g. minimizing area) and common design constraints for a given gate-level design library. The implementation costs are used in evaluating the topologies throughout the topology synthesis. The major drawback of single switch library approach is that it forces the topology synthesis methods to search the best topology with the assumption that all the switches comprising a topology will be implemented (synthesized) with a common design objective and common design constraints. Such assumption prevents them from exploring diverse combinations of the switches for a topology from the implementation perspective. To tackle this issue, we propose a topology synthesis method with multiple switch libraries, where the switch libraries are prepared with different design objectives and design constraints. The experimental results show that the power consumption and the area of optimal topologies can be saved by up to 67.1% and 27.2%, respectively, by the proposed method with negligible synthesis time 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.
