| Abstract | ISRO Satellite Centre (ISAC) is the lead centre of the Indian Space Research Organisation in the development and operationalisation of satellites for communication, navigation and remote sensing applications. A well orchestrated highly advanced embedded system plays a major role in success of all such satellites. Dynex MAR31750 was the processor used for our all GSAT, INSAT, IRS type of satellites. Now moved to HX1750 processor based CPU designed for standard AOCE of GSAT 17/18 programmes. The validation of this processor and result analysis of module time measurement and its automation are presented in this paper. Special attention is given on verification and comparison of results of Dynex processor and HX1750 processor. The onboard computational load increases as per the new requirements and to incorporate autonomy onboard. To accomplish all the computational requirements, time segment based design is adopted. Hence timing measurement of modules play a major role in evaluating the processor. This paper mainly states the realization of the same. |

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.
