| Abstract | State of the art FPGAs allow the implementation of small to medium sized Systems-on-Chip (SoCs) where configurability is key in order to achieve design goals. Thus, SoCs are frequently designed around soft extensible processors, which provide a tradeoff between design flexibility and fast time to market. This paper presents the impact of micro-architectural features on several design metrics of a multithreading extensible processor. Using the MiBench benchmark, it is shown how Custom Computational Units (CCUs) can significantly increase performance while providing lower power solutions than software-only implementations. An efficient architecture that facilitates the insertion of CCUs is described and the effect of multithreading and thread scheduling policies on the design metrics is also demonstrated. Results show that multithreading policies can have positive impact on key parameters (e.g., up to 20% increase on performance and up to 10% energy savings in the given application), depending on application characteristics as well as micro-architectural features. |

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.
