| Abstract | The interest in non-synchronous design of digital circuits is growing due to technology scaling into deep submicron transistor geometries and to the problems this scaling causes to keep synchronous design advantageous. To enable most non-synchronous styles, the C-element is a fundamental device that has to be available as logic primitive. A recently proposed design flow improved a standard cell library, adding to it a set of typical asynchronous cells. However, the original flow did not address low power cells explicitly, which is a requirement in many modern applications. This paper proposes the extension of the flow so that it can expand the cell set with low power components. To achieve this, the paper adds a new degree of freedom to cell design. The new standard cell set encompasses over 500 different C-element implementations. The cell set employs a 65nm commercial CMOS process and is fully compliant with the foundry standard cell library. A fully asynchronous RSA crypto core was designed with the new cells, producing savings of more than 35% in total power and more than 69% in leakage power. |

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.
