Abstract

　汎用ＯＳに改変を加えることなくコストの増大を抑制しながら、時間計測を正確に実行すること。この課題を解決するために、計時依頼部（１０１）は、希望の計測時間から予想遅延時間を減算し、得られた減算結果を依頼計測時間として、汎用ＯＳ部（１０８）に計時を依頼する。処理負荷検知部（１０２）は、計時依頼部（１０１）に希望の計測時間が入力された時点での汎用ＯＳ部（１０８）における処理負荷を検知する。予想遅延時間取得部（１０３）は、処理負荷検知部（１０２）によって検知された処理負荷と同一条件を遅延時間記憶部（１０４）から検索し、この条件に対応して記憶された遅延時間を予想遅延時間として取得する。遅延時間記憶部（１０４）は、過去に汎用ＯＳ部（１０８）が時間を計測した際に生じた遅延時間とその時の処理負荷とを対応付けて記憶している。
