AI Technical Summary
【0010】 本開示の実施例の技術的解決手段は、第1メモリからパッチデータを読み取り、パッチデータを解析して、パッチコードデータを取得する。パッチコードデータから、第2メモリ内のターゲットコードでのパッチ関数の位置を指示するための、少なくとも1つのパッチ関数に対応する第1アドレスを取得し、これにより、本開示の実施例の解決手段は、第1パッチコードの本体を第2メモリに記憶し、第1メモリには、パッチ関数の第1パッチコード自体でない、パッチ関数に対応する第1アドレスを記憶するため、第1メモリの容量ボトルネックを大幅に緩和し、第1メモリの容量が小さいことにより、修復可能なデータ量が少ないという問題を回避することができる。第1アドレスに対応するパッチ関数の第1パッチコードを実行し、パッチ実行時に、第1メモリから大量の命令をロードする必要がなく、直接第2メモリに固定化されたパッチ関数にジャンプするため、実行速度を向上させることができる。パッチ関数は、第2メモリのターゲットコード内に存在し、予め設定された機能修復関数であることもでき、機能拡張関数であることもできるため、設計の柔軟性が高く、パッチ関数は、単純な命令修復機能に限定されず、大規模なターゲットコードの修復又は機能拡張に対するニーズを満たすことができる。
