| Abstract | In this paper a fine-grained island style architecture is proposed based on crossbars of nanowires with diode-logic created by molecular devices. A multiple-bit access mechanism is the main requirement for the clusters in every island style architecture to provide inputs, outputs and configuration bits. Island style FPGA architecture with its rich interconnect capabilities seems to be a proper choice for high-level architectures in nanoscale devices. Providing appropriate access to all clusters inside such architectures to communicate with input, output and configuration signals is the main requirement in these structures. In this paper, a multiple-bit DMUX scheme is proposed to act as CMOS-Nano interface and facilitate the configuration and input/output transfer to the nanoscale crossbar structure of the clusters. Two different architectures for the multiple-bit DMUX are proposed. The first DMUX architecture uses nano-imprint technology to provide the required interconnections between nanowires in the architecture and hence is completely nanoscale while the second architecture uses CMOS wires as select lines of the DMUX. These two architectures are analyzed in terms of area overhead based on the number of CMOS and nanoscale wires used in them. The calculations show that both approaches are area efficient when compared to their CMOS counterpart. The estimates also show that for a wide variety of cluster sizes, area of a cluster, that can be configured as large number of lookup tables (LUTs), is significantly smaller than a single 4-input CMOS LUT (22 nm technology). The proposed nano architecture also has its novelty in structure of the clusters and the way these clusters can be used to implement multiple logic functions on them. |

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.
