| Abstract | Analysis of trade-offs between energy efficiency and latency is essential to generate designs complying with a given set of constraints. Improvements in FPGA technologies offer a myriad choices for power and performance optimizations. Various algorithm intrinsic parameters also affect these objectives. The design space is compounded by the available choices. This requires efficient techniques to quickly explore the design space. Current techniques perform Gate/RTL level or functional level power modeling which are slow and hence not scalable. In this work we perform efficient design space exploration using a high level performance model. We develop a semi-automatic design framework to generate energy efficiency and latency trade-offs. The framework develops a performance model given a high level specification of a design with minimal user assistance. It then explores the entire design space to generate the dominating designs with respect to energy efficiency and latency metrics. We illustrate the framework using convolutional neural network which gained significance due to its application in deep learning. We simulate a few designs from the dominating set and show that the performance estimation for the dominating designs are close to the simulated results. We also show that our framework explores 6000 design points per minute on a commodity platform such as Dell workstation as opposed to state-of-the-art techniques which explore at 50 to 60 design points per minute. |

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.
