| Abstract | This paper discusses performance of a winner-take-all neural network (WTANN) that is based on digital frequency-locked loops (DFLLs), especially its speed as well as its vector classification capability are studied. In the proposed WTANN input and weight vectors are conveyed by frequency-modulated signals, and neuron computation is carried out by the DFLL. Each DFLL uses a direct digital frequency synthesizer (DDS) as its local oscillator. Frequency resolution of signal generated by the DDS is decided by the size of internal register. Winner search operation is implemented by using frequency comparators distributed among all neurons, which makes it easier to increase the number of neurons. The proposed WTANN architecture was described by very high speed integrated circuit (VHSIC) hardware description language (VHDL) and its feasibility was tested and verified through simulations. Simulation results show that the proposed DFLL-based WTANN can find winner neuron faster than digital phase-locked Loop (DPLL) based WTANN. Another simulation was carried out by using IRIS and WINE data set to verify the classification performance of the WTANN. |

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.
