| Abstract | A new look-up-table (LUT) circuit combined with tunneling magneto-resistive (TMR) devices and MOS transistors is proposed for a power-aware FPGA, where the standby mode can be quickly changed to the active one. Since a TMR device is regarded as a variable resistor, any logic functions with external inputs and one-bit stored input can be performed by series and/or parallel connection of TMR devices and MOS transistors, which achieves a compact circuit implementation. The use of TMR-based logic-circuit structure makes circuit-configuration information still maintained without external nonvolatile memory even if the power supply is cut off, which realizes an instant standby/active-state capability. The combination of a dynamic current-mode circuitry and the TMR-based logic network also makes it possible to greatly reduce the dynamic power dissipation. A typical arithmetic-circuit design example using the proposed LUTs is discussed, and its advantages in terms of device counts, switching delay and power dissipation are demonstrated in comparison with a corresponding SRAM-based FPGA with external nonvolatile memory. |

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.
