| Abstract | Just-in-time (JIT) compilation has previously been used in many applications to enable standard software binaries to execute on different underlying processor architectures. However, embedded systems increasingly incorporate Field Programmable Gate Arrays (FPGAs), for which the concept of a standard hardware binary did not previously exist, requiring designers to implement a hardware circuit for a single specific FPGA. We introduce the concept of a standard hardware binary, using a just-in-time compiler to compile the hardware binary to an FPGA. A JIT compiler for FPGAs requires the development of lean versions of technology mapping, placement, and routing algorithms, of which routing is the most computationally and memory expensive step. We present the Riverside On-Chip Router (ROCR) designed to efficiently route a hardware circuit for a simple configurable logic fabric that we have developed. Through experiments with MCNC benchmark hardware circuits, we show that ROCR works well for JIT FPGA compilation, producing good hardware circuits using an order of magnitude less memory resources and execution time compared with the well known Versatile Place and Route (VPR) tool suite. ROCR produces good hardware circuits using 13X less memory and executing 10X faster than VPR's fastest routing algorithm. Furthermore, our results show ROCR requires only 10% additional routing resources, and results in circuit speeds only 32% slower than VPR's timing-driven router, and speeds that are actually 10% faster than VPR's routability-driven router. |

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.
