| Abstract | After its establishment as a new standard for still-image coding, JPEG-2000 is now in the stage of the exploration for efficient implementation in real-life systems. In this paper we focus on the implementation of the frontend part, i.e. the filtering processes performed by the discrete wavelet transform (DWT). The target platforms are programmable processors, since the modern evolution of their design positions them as good alternatives for efficient, flexible and fast time-to-market designs. As a result, to facilitate the incorporation of the new standard in such designs, we present experimental and theoretical results for the data-related cache misses that occur during the DWT, since it has been shown that these comprise the main bottleneck in this type of application. In addition to this, we also rank the presented designs with respect to the power efficiency, under a high-level power estimation scheme. To validate our models, apart from the simulation results, indicative experimental results are presented in superscalar and VLIW real-life architectures. |

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.
