Abstract
【解決手段】高速入力、高速出力、中低速の入力、中低速の出力を有する入出力構造が提供される。入力回路と出力回路の一方が選択され、もう一方が選択解除される。高速入出力回路は、例えば制御ライン入力に対してクリア信号のみを有して比較的単純であり、集積回路のコア内部の低速回路構成にインターフェースすることができる。中低速入力および出力回路は、例えば制御ライン入力としてプリセット、イネーブルおよびクリアを有してより柔軟であり、JTAGバウンダリ・テストを支援することができる。これらの並列の高速回路および低速回路はユーザによって選択可能であり、したがって、アプリケーションの要件によって、入出力構造は速度と機能の間で最適化される。
