This paper presents specification, evaluation results and applications of a hybrid architecture JTRON2.1, in which the Java runtime environment and a real-time OS coexist in order to utilize the Java language in the embedded systems requiring real-time processing. In JTRON2.1 specification, Java threads and realtime tasks cooperate through communication mechanisms. The communication mechanisms consist of attach classes, shared objects and stream communication. The first one provides methods by which Java threads can access to real-time resources. By the second one, realtime tasks can access to Java objects. The third one utilizes the Java stream to communicate with real-time tasks. The communication mechanisms are implemented by libraries on the real-time OS and the Java runtime environment. Using the libraries, the hybrid architecture is realized, where real-time processing is executed by real-time tasks on the real-time OS and non real-time processing is done by Java threads on the Java runtime environment.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"78","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"64","bibliographicIssueDates":{"bibliographicIssueDate":"2004-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG03(ACS5)","bibliographicVolumeNumber":"45"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
