| Abstract | GPUs and multicore CPUs are becoming common in today's embedded world of tablets and smartphones. With CPUs and GPUs getting more complex, maximizing hardware utilization and minimizing energy consumption are becoming problematic. The challenges faced in GPGPU computing on embedded platforms are different from their desktop counterparts due to the memory and computational limitations. This study evaluates the advantages of offloading Java applications to an embedded GPU. By employing two approaches namely, Java Native Interface (JNI-OpenCL) and Java bindings for OpenCL (JOCL) we allowed programmers to program an embedded GPU from Java. Experiments were conducted on a Freescale i.MX6Q SabreLite board which contains a quad-core ARM Cortex A9 CPU and a Vivante GC 2000 GPU that supports the OpenCL 1.1 Embedded Profile. The results show up to an eight times increase in performance efficiency by consuming only one-third the energy compared to the CPU-only version of the Java program. This paper demonstrates the performance and energy benefits achieved by offloading Java programs onto an embedded GPU. To the best of our knowledge, this is the first work involving Java acceleration on embedded GPUs. |

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.
