This paper proposes a software update scheme that uses broadcasting, i.e. the station broadcasts a differential between old and new firmwares and the automotive device updates its own old firmware to the new one based on the differential. The proposed scheme reforms bsdiff/bsupdate, existing tools for binary file updating, to resolve problems specific to automotive devices such as memory constraint and unstable power supply. We achieve in-place differential updating which does not require memory for the new binary and enable safe recovery from sudden power cuts by storing contexts periodically.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム(EMB)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-03-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2011-EMB-20"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":73463,"updated":"2025-01-21T21:54:20.340129+00:00","links":{},"created":"2025-01-18T23:31:25.957324+00:00"}
