| Abstract | In this paper we present a hardware/software co-design based computation platform for online data processing in particle physics experiments. Our goal is to ease and accelerate the development and make it universal and scalable for multiple applications, on the premise of guaranteeing high communicating and processing capabilities. The entire computation network consists of quite a few interconnected compute nodes, each of which has multiple FPGAs to implement specific algorithms for data processing. High-speed communication features including RocketIO multi-gigabit transceiver and Gigabit Ethernet are supported by FPGAs to construct internal and external connections. An embedded Linux operating system is fitted on the PowerPC CPU core inside the Xilinx Virtex-4 FX FPGA. Thus programmers can access hardware resources via device drivers and write application programs to manage the system from the high level. Furthermore measurements have been executed using the development board to investigate both communicating and processing performances of the system. Results show that the computation platform is able to communicate at a UDP/IP data rate of around 400 Mbps per Ethernet link, and the event selection engine could process an event stream of 148.1 MBytes/s at an interesting event rate of 25%. |

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.
