| Abstract | Several asynchronous system design tools are based on syntax-driven translation of behavioral specifications (e.g., Balsa, Haste). While they provide rapid design times, the performance of the resulting implementations is typically limited, in part because specifications written by designers often have limited concurrency due to unpipelined operation and unnecessary sequencing. To overcome these challenges, this paper proposes a "source-to-source'' transformation (i.e., code rewriting) of the original specification into a new one using a variety of concurrency-enhancing optimizations: (i) automatic parallelization, (ii) automatic pipelining, (iii) arithmetic optimization, and (iv) reordering of channel communication. Our approach has been integrated into an existing design flow, and applied to a suite of examples. Experimental results demonstrate that our approach correctly and efficiently rewrites the original specifications into highly concurrent ones. If code length is used as an indicator of designer effort, our approach reduces the required effort by a factor of 3.3x on average (up to 8.8x). Alternatively, the impact of our approach can be quantified by the throughput improvement achieved by optimizing the original specification: up to 59x speedup using our basic approach, and a further 5.2x using arithmetic optimization. |

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.
