| Abstract | In spite of significant advances in the development of low-power designs and power management techniques, power remains and will remain a first-class design constraint for mobile devices. The functionality integrated into mobile devices will only continue to grow with the increasing transition from PCs to super-phones. Power remains one of the critical hurdles to this transition, and without continued innovations in power management, the term "mobile" devices will be rendered moot. In addition to (and closely related to) power challenges in mobile devices are thermal challenges. Increasingly complex and rich functionality in mobile devices leads to higher power dissipation, and consequently, higher temperatures. However, thermal constraints are constant across successive device generations. Thermal limits, even more than power, will become the fundamental bottleneck to increasing the capabilities of such devices, making thermal management techniques crucial. This paper discusses some of the major challenges in power management and thermal management for current and next-generation mobile devices from a semiconductor industry perspective. Specifically, this paper discusses challenges in three areas: process-variability-aware power management, thermally aware power management and thermal management for mobile devices. Broadcom mobile chipsets feature multiple such advanced power and thermal management techniques, with active on-going research and development in each of these areas. |

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.
