| Abstract | In particular for applications where no repair is possible, e.g. space missions, high reliability is usually an important requirement. Long mission times and harsh environment are a challenge for electronic circuits, and particular error mitigation techniques have to be implemented in order to be able to cope with the expected error effects. Our approach instead is based on delay-insensitive asynchronous logic, more precisely on the four state logic (FSL) design style and partial reconfiguration. Compared to synchronous circuits, FSL implies a considerable area overhead, but also provides some hidden and usually unused features. In this paper an overview is presented, how these features can be utilized in order to implement self-healing circuits in a very efficient way. As the FSL design style plays a central role in the presented concept, first an introduction to FSL is provided. Subsequently the self-healing approach will be explained showing how the above mentioned tasks to achieve self-healing are realized. The paper concludes with the current implementation status and open problems. |

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.
