| Abstract | Monolithic integration of photodetectors, analog-to-digital converters, data storage, and digital processing can improve both the performance and the efficiency of future portable image products. However, digitizing and processing a pixel at the detection site presents the design challenge to deliver a system with the required performance at the lowest cost, not just a system with the highest performance. This paper analyzes the area-time efficiency, the area efficiency, and the energy efficiency of a mixed-signal, SIMD focal plane processing architecture that executes front-end image applications with neighborhood processing. Implementations of the focal plane architecture achieve up to 81x higher area efficiency and up to 11x higher energy efficiency when compared to traditional TI DSP chips. Higher efficiency ratings are required to maintain portability while addressing technology limitations such as interconnect wiring density, heat extraction, and battery life. Systems can be implemented with a less expensive fabrication technology by increasing the number of pixels per processing element (PPE). |

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.
