| Abstract | This paper presents a novel (low arithmetic unit count) hardware architecture for performing lifting-based JPEG2000's 5/3 Discrete Wavelet Transform (DWT). The architecture is built around parallel Shift-Accumulator Arithmetic Logic Units (ALUs) which can encode (with implicit embedded extension) up to five levels of transformation. The proposed architecture, which consists of three adders, two subtractor-adders and five shifters, has a significantly lower hardware count compared to the architectures proposed by K. Andra et. al. (2002) and C-J. Lian et. al. (2001). In addition, the architecture has an efficient memory organisation, which uses lesser amount of embedded memory for processing and buffering. In this paper, we present the architecture and demonstrate that it closely adheres to the JPEG2000's specification while reducing the hardware requirements and hence area and power consumption. |

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.
