600 個のコア間通信データのうち 9 割以上のデータが同期不要であることが特定できた．また，並列化した制御ソフトをマルチコアマイコンに実装し，要求されるリアルタイム性能が満たされていることを HILS

control are increasing, for instance to comply the exhaust emission regulations and reduce gasoline consumption. These requirements for engine control system with high performance lead to multicore approaches to reach the desired features. However, the necessary migration of software from single core to multicore systems raises several problems. In particular, an ensuring of real-time performance of engine control software in multicore environment is tough issue due to frequent inter-core synchronizations caused from a large number of inter-core communication data. In this paper, we propose a parallelism improvement method with performance requirements of control for engine control software. The feature of our method is to identify the inter-core data which doesn't need core synchronization according to the requirements of data delay, stability and coherency. We applied our method to legacy engine control software in order to migrate to multicore which has two cores. The first core executes periodic tasks, and the second core executes event tasks which are triggered by an engine rotation. The result indicated that more than ninety percent data out of approximately six hundreds inter-core communication data doesn't need synchronization mechanism. We evaluated the parallelized engine control software with HILS (Hardware-in-the loop simulation), the software satisfied requirements of real-time performance.","subitem_description_type":"Other"}]},"item_29_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"63","bibliographic_titles":[{"bibliographic_title":"組込みシステムシンポジウム2016論文集"}],"bibliographicPageStart":"55","bibliographicIssueDates":{"bibliographicIssueDate":"2016-10-13","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2016"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T06:21:39.472568+00:00","created":"2025-01-19T00:45:04.682051+00:00","links":{},"id":175022}
