Target Language Compiler

Target Language Compiler を使用したブロックのコード生成動作の定義

Target Language Compiler (TLC) はコードジェネレーターに不可欠な部分です。TLC を使用して生成コードをカスタマイズします。カスタマイズによって、プラットフォーム固有のコードを生成したり、パフォーマンス、コードサイズ、既存のメソッドとの互換性用に独自のアルゴリズムの変更を組み込むこともできます。

Target Language Compiler を使用して、以下のことを実行できます。

システムターゲットファイルで指定されたオプションのセットをカスタマイズ。
S-Function ブロック用にコードをインライン化。
追加またはさまざまなタイプのファイルの生成。

TLC の基本については、Target Language Compiler Basicsを参照してください。
