| Abstract | This paper presents a scheduling & resources sharing technique for adaptive LMS (Least-Mean-Square) filter with low power consumption and low resources utilization. It used an 8-bit fixed-point arithmetic representation for the adaptive filter system based on FPGA. The design has been synthesized and simulated in Xilinx ISE. LMS algorithm is widely used in the adaptive filter for noise cancellation system or hearing aid system. We verified the parameter step size u, through simulated the LMS algorithm on MATLAB. And then, we implemented and simulated the original LMS circuit and the proposed LMS circuit which use the scheduling & resources sharing technique design in Xilinx ISE. We found that the proposed circuit uses resources less than the original circuit. Based on the XPower Analyzer tool, the power consumption is estimated. The results showed that the proposed circuit dissipates less power than the original circuit. It nearly economizes 36.4% power consumption compared with the original one. |

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.
