| Abstract | Three-dimensional (3-D) integrated circuits have emerged as promising candidates to overcome the interconnect bottlenecks of nanometer scale designs. While they offer several other advantages, it is expected that the benefits from this technology can potentially be off-set by thermal considerations which impact chip performance and reliability. The work presented in this paper is the first attempt to study the performance benefits of 3-D technology under the influence of such thermal constraints. Using a processor-cache-memory system and carefully chosen applications encompassing different memory behaviors, the performance of 3-D architecture is compared with a conventional planar (2-D) design. It is found that the substantial increase in memory bus frequency and bus width contribute to a significant reduction in execution time with a 3-D design. It is also found that increasing the clock frequency translates into larger gains in system performance with 3-D designs than for planar 2-D designs in memory intensive applications. The thermal profile of the vertically stacked chip is generated taking into account the highly temperature sensitive leakage power dissipation. The maximum allowed operating frequency imposed by temperature constraint is shown to be lower for 3-D than for 2-D designs. In spite of these constraints, it is shown that the 3-D system registers large performance improvement for memory intensive 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.
