The typical embedded system configures the processor through the bus directly connected to devices with the primitive level interface architecture. In the software architecture design, it is one of important themes to eliminate any overheads caused by the frequent interaction between RTOS and tasks. This manuscript proposes three methods as follows: First is to implement the reduction of the overhead to switch the context with the algorithm for redundancy to invoke tasks. Second is to implement the environment to integrate several tasks into the single task for shortening effective intervals of the task activation. Third is to prevent the complexity of task scheduling caused by the algorithm for redundancy.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2013-OS-124"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
