Abstract | Stream processing has emerged as an important model of computation in the context of multimedia and communication sub-systems of embedded System-on-Chip (SoC) architectures. The dataflow nature of streaming applications allows them to be most naturally expressed as a set of kernels iteratively operating on continuous streams of data. The kernels are computationally intensive and exhibit large amounts of data and instruction level parallelism. Streaming applications are mainly characterized by real-time constraints that demand high throughput and data bandwidth with limited global data reuse. Conventional architectures fail to meet these demands due to their poorly matched execution models and the overheads associated with instruction and data movements. We present StreamEngine, an embedded architecture for energy-efficient computation of stream kernels. StreamEngine introduces an instruction locking mechanism that exploits the iterative nature of the kernels and enables fine-grain instruction reuse. We also adopt a Context-aware Dataflow Execution model to exploit instruction-level and data-level parallelism within the stream kernels. Each instruction in StreamEngine is locked to a Reservation Station and maintains a context that is updated upon execution; thus instructions never retire from the RS. The entire kernel is hosted in RS Banks close to functional units for energy-efficient instruction and operand delivery. We evaluate the performance and energy-efficiency of our architecture for stream kernel benchmarks by implementing the architecture with TSMC 45nm process, and comparison with an embedded RISC processor. |

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.
