But these operations are difficult. In this paper, we propose a system that divides a user task which includes some threads into some functional modules at a run time and executes these divided tasks in parallel. In this system, a thread which frequently accesses a particular device is executed in the module which has that device. We consider that this system can reduce inter-module communications between server threads which control the device and user threads. We implemented this system into μ-PULSER, an operating system for personal robot. We evaluated some basic thread operations in this system. The result shows that the cost of creating a remote thread is 2.7 times as long as that of creating a local thread. And we also evaluated the rate of inter-module communications. The results shows that it was reduced to 50% and that the response time of a event is reduced to 8.0%.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"12","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"7","bibliographicIssueDates":{"bibliographicIssueDate":"1996-03-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23(1995-ARC-117)","bibliographicVolumeNumber":"1996"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
