今後の展望

第 6 章結論

6.2 今後の展望

本研究の今後の展望として以下のことに取り組みたい．

•

リアルタイムシステムに適用する上で十分でないところを解決

•

協調分散システムへの対応

•

より実践的な組込みソフトウェアのケーススタディへの適用

本研究では，レイヤアクティベーション時のリアルタイム性確保のために

4

章の取り組みを行ったが，実際のリアルタイムな組込みソフトウェアに適用するためには十分ではない．例えば，レイヤアクティベーションと振る舞い実行との間で同期を行うための排他制御について考慮できていないため，

今後このような機能を追加していきたい．

組込みソフトウェア開発において，ROS⁴⁹⁾ のような協調分散システムが注目されており，それに対応することは重要である．そのためには，複数のプロセスをまたいでレイヤを扱うような機構が必要であり，その機能について考慮していきたい．

最後に，より実践的な組込みソフトウェアにこれまで提案してきたものを適用し，新たな課題の発見・解決に取り組みたい．

2.5

節で示した通り，

COP

の組込みソフトウェアへの適用事例は少ないため，新たなケーススタディが必要とされており，新たなケーススタディは有用である．
