| Abstract | We present Synchroscalar, a tile-based architecture forembedded processing that is designed to provide the flexibilityof DSPs while approaching the power efficiency ofASICs. We achieve this goal by providing high parallelismand voltage scaling while minimizing control and communicationcosts. Specifically, Synchroscalar uses columnsof processor tiles organized into statically-assignedfrequency-voltage domains to minimize power consumption.Furthermore, while columns use SIMD control to minimizeoverhead, data-dependent computations can besupported by extremely flexible statically-scheduled communicationbetween columns.We provide a detailed evaluation of Synchroscalar includingSPICE simulation, wire and device models, synthesisof key components, cycle-level simulation, andcompiler- and hand-optimized signal processing applications.We find that the goal of meeting, not exceeding, performancetargets with data-parallel applications leads todesigns that depart significantly from our intuitions derivedfrom general-purpose microprocessor design. Inparticular, synchronous design and substantial global interconnectare desirable in the low-frequency, low-powerdomain. This global interconnect supports parallelizationand reduces processor idle time, which are critical to energyefficient implementations of high bandwidth signalprocessing. Overall, Synchroscalar provides programmabilitywhile achieving power efficiencies within 8-30X ofknown ASIC implementations, which is 10-60X better thanconventional DSPs. In addition, frequency-voltage scalingin Synchroscalar provides between 3-32% power savingsin our application suite. |

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.
