2. ロードマップ案内🎯

今回の講義はロードマップ「システムソフトウェア開発者向けのArm - advanced course 」に含まれる講義。


体系的にArmアーキテクチャ（Armv8-A、Armv7-A）を学びたい方はロードマップ（全体講義の30％割引）を活用してください。ちなみに、Armアーキテクチャロードマップ（作者直江全体）はBasic CourseとAdvanced Course 2つで構成されています。

最新のシステムソフトウェアから
最も重要な Arm アーキテクチャ

スマートフォンはもちろん、AI用SoCシステム半導体、電気自動車Automotive（自動運転、インフォテインメント）、クラウドサーバーやMacBookで使用されるArmプロセッサは、すべてArmv8-Aベースの64ビットCortex-Aプロセッサ（Cortex-A53、Cortex-A57、Cortex-A72など）です。現在、システムソフトウェア業界で最も必要な基盤知識が求められる内容がArmv8-Aアーキテクチャと見なすことができます。

高度なシステムSW開発者になる第一歩！
キャッシュの動作原理を理解する🙋‍♂

しかし、高度なシステムソフトウェア開発者になるためには、Armアーキテクチャを構成する主な機能の間にメモリを管理する方法をよく理解する必要があります。メモリを管理する方法の鍵は、「仮想メモリシステム」、「キャッシュ動作原理」、および「メモリモデルとバリア」です。

それでは、「キャッシュの動作原理」をなぜよく知る必要がありますか？

1⃣まず、メモリ階層では、キャッシュはCPUコアとメインメモリの中間にあります。キャッシュはシステムのパフォーマンスに大きな影響を及ぼすことができ、キャッシュの基本構造とマルチレベルキャッシュの構造そしてキャッシュルックアップはシステムの性能を育てるための基盤知識です。

2⃣第二に、キャッシュの構造をよく知ることで、キャッシュヒットを活用したキャッシュのフレンドリーなコードを書くことができます。たとえば、頻繁に使用されるルーチンは、特定のCPUコアでのみ実行されるように設計できます。その結果、キャッシュミスを減らすことができ、パフォーマンスを最適化したプログラミングを行うことができます。

3⃣第三に、キャッシュの動作原理はクラッシュ問題をうまくデバッグできる基盤知識です。本番プロジェクトを続行すると、キャッシュが壊れたり、「キャッシュライン Fill」の動作にエラーが発生する可能性があります。このようなキャッシュに関する問題をうまくデバッグできる基盤知識が、キャッシュの構造と動作方式です。

4⃣4番目に、キャッシュに関する内容をよく知ることで、技術面接をよく見ることができます。特にペプリス社（システム半導体）技術の面接でキャッシュに関する質問がたくさんあります。

このようなことを学びます。

キャッシュの基本概念を簡単かつ詳細に説明し、CPUキャッシュの構造について紹介します。

ほとんどの場合、CPUで適用されるマルチレベルキャッシュについて説明し、大きな図でメモリシステム内のキャッシュがどのフローで処理されるかを分析します。

キャッシュのコンポーネントを詳細に説明し、TRACE32デバッグプログラムを使用してキャッシュ情報（キャッシュラインと追加情報）を説明します。

マルチレベルキャッシュに適用されるキャッシュポリシー（ライトバック、ライトスルー）を理解しやすく詳細に説明します。

Arm アーキテクチャで使用されるキャッシュ固有の用語を紹介し、キャッシュに関連する API が現行プロジェクトでどのように使用されるかを説明します。
