| Abstract | In ultrasound imaging, synthetic aperture imaging (SAI) supported by full aperture and full frame rate is desirable for an improved resolution, SNR and real time imaging, however, real time implementation requires RF data from all channels have to be transferred to all scan-lines in real time so that implemented hardware become very complex and this complexity hindered to the practical implementation. In this paper, a new intuitive and simple architecture which minimizes this complexity, especially the interconnections between Rx channel (from ADC) and ASIC, is presented. This architecture contains high speed serial data transfer (employing low voltage differential signaling - LVDS), division of the channels into groups and RF data sharing bus. Also modular structure is employed so that ASIC can be repeatedly placed for easy system implementation. Chip area (CA) and power consumption (PC) have been estimated for the system with proposed architecture and it is been confirmed that ASIC can be constructed using a 0.13 um semiconductor process. |

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.
