| Abstract | Given the high level description of a task, many different hardware modules may be generated while meeting its behavioral requirements. The characteristics of the generated hardware can be tailored to favor energy efficiency, performance, accuracy or die area. The inherent trade-offs between such metrics need to be explored in order to choose a solution that meets design and cost expectations. We address the generic problem of automatically deriving a hardware implementation from a high-level task description. In this paper we present a novel technique that exploits previously explored implementation design spaces in order to find optimal trade-offs for new high-level descriptions. This technique is generalizable to a range of high-level synthesis problems in which trade-offs can be exposed by changing the parameters of the hardware generation tool. Our strategy, based upon machine learning techniques, models the impact of the parameterization of the tool on the target objectives, given the characteristics of the input. Thus, a predictor is able to suggest a subset of parameters that are likely to lead to optimal hardware implementations. The proposed method is evaluated on a resource sharing problem which is typical in high level synthesis, where the trade-offs between area and performance need to be explored. In this case study, we show that the technique can reduce by two orders of magnitude the number of design points that need to be explored in order to find the Pareto optimal solutions. |

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.
