| Abstract | Minimizing power consumption is vitally important in embedded system design; power consumption determines battery lifespan. Ultra-low-power designs may even permit embedded systems to operate without batteries by scavenging energy from the environment. Moreover, managing power dissipation is now a key factor in integrated circuit packaging and cooling. As a result, embedded system price, size, weight, and reliability are all strongly dependent on power dissipation. Recent developments in nanoscale devices open new alternatives for low-power embedded system design. Among these, single-electron tunneling transistors (SETs) hold the promise of achieving the lowest power consumption. Unfortunately, most analysis of SETs has focused on single devices instead of architectures, making it difficult to determine whether they are appropriate for low-power embedded systems. Evaluating the use of SETs in large-scale digital systems requires novel architectural and circuit design. SET-based design imposes numerous challenges resulting from low driving strength, relatively large static power consumption, and the presence of reliability problems resulting from random background charge effects. We propose a fault-tolerant, hybrid SET/CMOS, reconfigurable architecture, named IceFlex, that can be tailored to specific requirements and allows tradeoffs among power consumption, performance requirements, operation temperature, fabrication cost, and reliability. Using IceFlex as a testbed, we characterize the benefits and limitations of SETs in embedded system designs. In particular, we focus on the use of SETs in room-temperature ultra-low-power embedded systems such as wireless sensor network nodes. We also consider high-performance applications such as multimedia consumer electronics. We see this work as a first step in determining the potential of ultra-low-power embedded system design using SETs. |

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.
