| Abstract | 3D IC is a promising technology to meet the demands of high throughput, high scalability, and low power consumption for future generation integrated circuits. One way to implement the 3D IC is to interconnect layers of two-dimensional (2D) IC with Through-Silicon Via (TSV), which shortens the signal lengths. Unfortunately, while TSVs are bundled together as a cluster, the crosstalk coupling noise may lead to transmission errors. As a result, the working frequency of TSVs has to be lowered to avoid the errors, leading to narrower bandwidth that TSVs can provide. In this paper, we first derive the crosstalk noise model from the perspective of 3D chip and then propose ShieldUS, a runtime data-to-TSVs remapping strategy. With ShieldUS, the transition patterns of data over TSVs are observed at runtime, and relatively stable bits will be mapped to the TSVs which act as shields to protect the other bits which have more fluctuations. We evaluate the performance of ShieldUS with address lines from real benchmark traces and data lines of different similarities. The results show that ShieldUS is accurate and flexible. We further study dynamic shielding and our design of Interval Equilibration Unit (IEU) can intelligently select suitable parameters for dynamic shielding, which makes dynamic shielding practical and does not need to predefine parameters. This also improves the practicability of ShieldUS. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
