an Android terminal, as well as fast execution of Java programs, coping with many kinds of network protocol and flexible connection of various sensors are needed. For that purpose, Reconfigurable Android with an FPGA is proposed to explore its availability and possibility. In this paper, a concept of Reconfigurable Android is introduced. We have implemented an FPGA accelerator, which realizes higher performance by executing a part of a Java source code executable in hardware, to accelerate Java execution in an Android mobile terminal. Between an Intel Atom processor which executes a Dalvik virtual machine and an FPGA accelerator, we have implemented PCI Express interface which performs high speed communication of 150 MByte/sec with DMA transfer in our experimental environment. Moreover, Acceleration of Android with an FPGA accelerator is described. Communication performance between a processor and an FPGA has been measured and the performance with the acceleration is evaluated.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2751","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2740","bibliographicIssueDates":{"bibliographicIssueDate":"2012-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"53"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:38:22.556390+00:00","id":87759,"links":{}}
