| Abstract | Recently, researchers have shown an increased interest in using task-level pipelining to accelerate the overall execution of applications mainly consisting of producer-consumer tasks. This paper proposes optimization techniques for enhancing our approach to pipeline the execution of producer-consumer tasks in FPGA-based multicore architectures with reductions in the number of accesses to external memory. Our approach is able to speedup the overall execution of successive, data-dependent tasks, by using multiple cores and specific customization features provided by FPGAs. We evaluate the impact in the performance of task-level pipelining when using different hash functions and optimization schemes in the inter stage buffer (ISB). The optimizations proposed in this paper were evaluated with FPGA implementations. The experimental results show the efficiency of a simple scheme to reduce external memory accesses and the suitability of the hash function being used. Furthermore, the results reveal noticeable performance improvements for the set of benchmarks being used. |

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.
