| Abstract | The Spring real-time system and environment provides methods for program representation and corresponding run-time system support that allow programs to meet the predictability demands of complex real-time applications. The primary objective of the work described in this paper is to present the experiences gained and the lessons learned from porting a real-world, real-time application to make it predictable and flexible. The exercise has also provided a test case which helps to answer questions about the completeness and ease of use of software development tools that have been developed to provide for flexibility while achieving real-time guarantees. This test case is derived from an existing real-time application in industry-a robotic work-cell that is currently in use for the assembly of circuit boards. From our experience with this reengineering exercise, we believe that a user must possess a good understanding of the following: (1) the general properties of the target hardware-for effective process and resource layout, and (2) the shared resource usage and interprocess communication, and, more generally, the statements that cause processes to suspend-for efficient run-time representation of the tasks. Tools that help the user obtain this understanding and perform detailed timing analysis are essential. Although the algorithms and tools used in the reimplementation were developed in the context of the Spring real-time environment, we believe that the lessons learned from this experiment will be useful not only to potential users of Spring, but also to real-time practitioners at large. |

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.
