| Abstract | Field-Programmable-Gate-Arrays are used increasingly to speed up applications in various fields of science. But as modern digital designs integrate hundreds of interconnected processing and memory units, the need for a higher level of abstraction to handle their descriptions is indisputable. This paper presents a beyond-RTL concurrent hardware description language that combines both Finite-State Machine (FSM) and constraint programming paradigms. At the featured level of abstraction, the user describes dynamic connections between data sources and sinks that may not always be ready to send or receive data tokens. The high-level description methodology enables a comprehensible description of behaviors such as data transfer synchronization, exclusivity, priority and constrained scheduling by the means of logical-implication rules constraining the data transfers authorizations. Dynamically connecting resources with potential combinatorial dependencies may lead to instability or deadlock. Such situations are automatically detected and fixed by the proposed compiler that generates a dedicated control-circuit optimizing the number of transfers that can be authorized at each clock cycle. The proposed design automation methodology is applied to the problem of deeply-pipelined vector reduction. A pipelined floating point accumulator and a matrix multiplication circuits are described with a few lines of code and automatically compiled into an FPGA. Results show that the synthesis results are comparable to those obtained with hand-written RTL but with much lower effort and time. |

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.
