| Abstract | This paper describes the development and real-time, fixed-point implementation of a Multiband Dynamic Range Compression (MDRC) algorithm on a 16 bit fixed-point platform-Texas Instrument's TMS320C54X. This algorithm has been designed primarily for use in hearing aid applications. It has been implemented on a prototype evaluation system that operates by default in a stereo mode with a minimum sampling rate of 20 KHz per channel. The paper also describes a new algorithm development software environment developed at Texas Instruments to facilitate the task of implementing complex Digital Signal Processing (DSP) algorithms on its DSP chips. This tool is known as eXpress DSP Algorithm Standard (XDAIS). Developing an algorithm that is XDAIS compliant facilitates the easy integration of the algorithm into a system. It also simplifies porting the algorithm to other applications or systems. For example, the XDAIS compliant MDRC algorithm, designed originally for hearing aid applications, could easily be ported for other audio or sensor data processing applications. |

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.
