| Abstract | This paper presents a new four moduli residue number system of the form $\{2^{k},$ $2^{n}-1,$ $2^{n+1}-1\},$ n d k d 2n, which is an enhancement of the popular four-moduli set $\{2^{n},2^{n}-1,2^{n},2^{n+1}-1\}$ (for even n). Our k-mod4 moduli set achieves a higher dynamic range and a better balancing of the binary channels. Using the proposed k-mod4 moduli set helps in reducing the hardware complexity of arithmetic circuits compared with other four-moduli sets for the same performance. Additionally, we provide a reverse converter design, whose hardware complexity and performance are shown to be better than the existing reverse converters for the same dynamic range. Experimental results comparing RNS multiply and accumulate units implemented using the proposed four-moduli set with the state-of-the-art balanced four-moduli sets, show large improvements in area (46%) and power (43%) reduction for various dynamic ranges. This makes our k-mod4 moduli set ideal for digital filters implementation. |

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.
