| Abstract | Software messaging frameworks help avoid errors and reduce engineering effort in building distributed systems by (i) providing an interface definition language (IDL) to precisely specify the structure of the message (the message schema) and (ii) automatically generating the serialization and deserialization functions that transform user data structures into binary data for sending across the network and vice versa. Similarly, a hardware-accelerated system that consists of host software and multiple FPGAs, could also benefit from a messaging framework to handle messages both between software and FPGA and also between different FPGAs. The key challenge for a hardware messaging framework is that it must be able to support large messages with complex schema while meeting critical constraints such as clock frequency, area, and throughput. We present HGum, a messaging framework for hardware accelerators that meets all the above requirements. HGum is able to generate high-performance and low-cost hardware logic by employing a novel design that algorithmically parses the message schema to perform serialization and deserialization. Our evaluation of HGum shows that it not only significantly reduces engineering effort but also generates hardware with comparable quality to manual implementation. |

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.
