| Abstract | Low-power design became crucial with widespread use of the embedded systems. The embedded processors need to be efficient in order to achieve real-time requirements with low power consumption for specific algorithms. As the superset of traditional very long instruction word (VLIW) architecture, the main advantages of transport triggered architecture (TTA) are its simplicity and flexibility. In TTA processors, the special function units can be utilized to increase performance or reduce power dissipation. Asynchronous circuits have characteristic of low power consumption and it is possible to exploit this characteristic to design embedded processors. In this article, we designed a low-power embedded processor using asynchronous function units. The processor core is globally synchronous and locally asynchronous implementation using not only synchronous function units but also asynchronous function units. We also presented an efficient design flow that use asynchronous circuits in TTA framework, which is only a synchronous design environment. The test result shows that this processor has lower power dissipation than its pure synchronous version that only uses synchronous function units. |

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.
