In such systems, partitioning is necessary in order to prevent the influence between functions having different reliability. Regarding the processor and memory, partitioning can be realized by using the memory protection function of RTOS. On the other hand, regarding peripheral devices, it is common to prepare for each function to ensure reliability. However, it is difficult to prepare network devices for each function due to its cost, therefore, it is necessary to share network devices between functions having different reliability. Hence, it is necessary to have a method for securely sharing a single network device between such functions. In this paper, we propose the method to share Ethernet controller between functions. We applied the device protection mechanism called Protection Wrapper to the existing Ethernet controller, and expand controller for sharing, then it becomes possible for each function to use one Ethernet controller independently. As a result of using the method we propose, compared to the case of assigning Ethernet controller to each function, echo back time was increased by 1.7%, and hardware area was decreased by 23%.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1476","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1464","bibliographicIssueDates":{"bibliographicIssueDate":"2018-08-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":190821,"updated":"2025-01-20T01:02:25.602670+00:00","links":{}}
