| Abstract | Fault tolerance techniques implemented at software level have been widely studied as an approach to improve reliability in processor-based systems. This paper presents a fault injection software-based methodology to emulate soft errors in processors running operational systems. The proposed method aims to accelerate the analysis of complex systems under soft errors in order to assist the development of fault tolerance mechanisms. In order to validate the proposed methodology, a simulator was implemented based on QEMU software. QEMU emulates a large number of well-known microprocessor architectures with a full system composed by memory and I/O devices. A case-study for an operational system - the Real Time Operating System (RTEMS) - running in X86 architecture was designed in the QEMU platform and faults were injected. Results show the susceptibility of the registers to faults and can guide designers in the fault tolerance techniques implemented at software level. |

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.
