【0009】 本開示の上記実施形態に係るシステムオンチップ上の機能コンポーネントを再起動する方法、装置及び電子機器によれば、システムオンチップ上の第1の機能コンポーネントの状態が第1の状態(即ち異常状態)であることを検出した場合、第1の機能コンポーネントの第1のバスインターフェースと共有バスとをアクセス遮断させて、第1の機能コンポーネントの共有バスへのアクセスを阻止させ、異常な第1の機能コンポーネントによる共有バスへの予期しないアクセスが発生することを回避することができ、それにより、他のオペレーティングシステム及び共有バスに接続された他の機能コンポーネントへの悪影響を回避することができる。さらに、アクセス遮断の場合、第1の機能コンポーネントを再起動することにより、第1の機能コンポーネントを異常状態から第2の状態(即ち、正常動作状態)に変換させ、第1の機能コンポーネントが正常に回復された後、第1の機能コンポーネントの第1のバスインターフェースと共有バスとのアクセス遮断を解除することにより、第1の機能コンポーネントを共有バスに正常的にアクセス可能であるようにし、共有バスの他のオペレーティングシステムの実行に影響を与えることなく、異常が発生した第1の機能コンポーネントを再起動して、第1の機能コンポーネントの共有バスへの正常的なアクセスを回復させることを実現し、マルチオペレーティングシステムのシステムオンチップの全体的な安定性を効果的に向上させる。例えば、システムオンチップは、コックピット·ドライビング統合システムであり、1つのシステムオンチップには、少なくとも2つのオペレーティングシステム(例えば、1つのインテリジェントコックピット用のオペレーティングシステムと1つのインテリジェントドライブ用のオペレーティングシステム)を同時に実行し、本開示の一実施形態の機能コンポーネントの再起動方法により、いずれか1つのオペレーティングシステムの異常により、システムオンチップ上の1つ又は複数の機能コンポーネントに異常が発生した場合、別のオペレーティングシステムの実行に影響を与えることなく、異常な機能コンポーネントを正常動作状態に回復させて、別のオペレーティングシステムの安定性を確保することができる。
