Abstract | Recently new Residue Number Systems (RNS) moduli sets have been proposed in order to increase the dynamic range and reduce the width of channels, therefore, reducing the processing time and further exploiting the carry-free characteristic of the modular arithmetic. In this paper we propose improved units for addition, subtraction, and multiplication in RNS for modulo {2^n+-k}. With this work, the somewhat disregarded field of RNS unit design is covered, encouraging the development of moduli sets with channels other than the traditional {2^n}, {2^n+-1} modulo. In order to evaluate the performance of the proposed structures, they are compared with the well known units for modulo {2^n}, {2^n+-1}, and {2^n+-3}. These structures allow to implement generic units for modulo {2^n+-k}, in the case of modular multiplication it is achieved the same critical path delay and merely 4% of increase on area resources, when compared with the dedicated structure presented in the state-of-art for modulo {2^n+-3}. |

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.
