| Abstract | This tutorial will present recent results in robust low power computing. The perspective will be microarchitectural: what limitations does it put on the microarchitecture and what can the microarchitect do to reduce the dependency on power and improve robustness? The tutorial will start with a technology overview that charts future trends in power and reliability. We will present a summary of prior research in dynamic power reduction in microarchitectures, and give some examples of industrial solutions. We will also review prior research in microarchitectural reduction of leakage performed by us and others. While the continued scaling that Moore's Law predicts is in many ways good for reducing power, scaling also reduces reliability by increasing uncertainty in device performance. Therefore, in order to take advantage of scaling, it will be necessary to compute in the presence of various types of silicon-related faults. Two that are particularly important are single-event upsets, and, even more serious, gates that will not meet their specifications. We will review techniques to provide robustness in light of these trends. In particular, we will revisit techniques developed by the fault-tolerant community as well as newer ideas in timing speculation, exemplified by our Razor research.The tutorial is intended for computer architects and circuit designers interested in a better understanding of current reliability challenges and emerging technologies to address them. |

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.
