| Abstract | Recently, the 3-D stacked integrated circuit technology has been expected to overcome the limitations in the design of the 2-D implemented microprocessors. This paper examines the potential of 3-D integration in design and implementation of large-scale arithmetic units. In this paper, 3-D stacked parallel multipliers with various operand sizes are designed, and the effect of circuit scale on the performance of 3-D stacked multipliers is discussed. In the design of a large-scale parallel multiplier, a lot of through-silicon-vias are required by the conventional partitioning pattern. This paper proposes a partitioning pattern suitable for a large-scale 3-D stacked parallel multiplier. The proposed partitioning pattern aims to reduce the number of TSVs with a large-scale parallel multiplier. Based on the proposed partitioning pattern, 3-D stacked 32, 64, and 128-bit multipliers are designed and evaluated. The proposed partitioning pattern achieves a 13.4% reduction in critical path delay and a 10.4% reduction in power consumption compared to the 2-D implementation, in the case of an 128-bit four-layer implemented 3-D stacked multiplier. |

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.
