Abstract
(EN)
The standby power consumption of a first thread, in the case that the first thread is executed after a second thread, is calculated by multiplying the execution time of the second thread by the standby power consumption per unit of time of the first thread. In addition, the standby power consumption of the second thread, in the case that the second thread is executed after the first thread, is calculated by multiplying the execution time of the first thread by the standby power consumption per unit of time of the second thread. The standby power consumption of the first thread and the standby power consumption of the second thread are compared, and the order of execution for the first thread and the second thread is determined on the basis of the comparison result.

On calcule la consommation d'énergie de veille d'un premier fil, dans le cas où ce premier fil est exécuté après un deuxième fil, en multipliant le temps d'exécution du deuxième fil par la consommation d'énergie de veille par unité de temps du premier fil. De plus, on calcule la consommation d'énergie de veille du deuxième fil, dans le cas où le deuxième fil est exécuté après le premier fil, en multipliant le temps d'exécution du premier fil par la consommation d'énergie de veille par unité de temps du deuxième fil. On compare la consommation d'énergie de veille du premier fil à la consommation d'énergie de veille du deuxième fil, et on détermine l'ordre d'exécution du premier fil et du deuxième fil d'après le résultat de la comparaison.

 第2のスレッドの実行時間と第1のスレッドの単位時間当たりの待機電力とを乗算することにより、第2のスレッドのつぎに第1のスレッドが実行された場合の第1のスレッドの待機電力を算出する。そして、第1のスレッドの実行時間と前記第2のスレッドの単位時間当たりの待機電力とを乗算することにより、第1のスレッドのつぎに第2のスレッドが実行された場合の第2のスレッドの待機電力を算出する。第1のスレッドの待機電力と第2のスレッドの待機電力とを比較し、比較結果に基づいて第1のスレッドと第2のスレッドとの実行順を決定する。
