Intel 8080 用のエミュレーターを作成しました。実装した命令が正しいかどうかを確認したいと思います。テストスイートまたは各命令が正しいかどうかをテストする方法はありますか?
私のエミュレータはCで書かれています。

残念ながら、大騒ぎのリンクはすべて死んでいます。そのため、リンクに依存しない、より包括的な回答を投稿してみます。
あなたが探しているのは、一連の 8080/8085 CPU 診断演習です。私は、非常に包括的なテスト スイートを構成する 3 つを見つけました。
- Microcosm Associates による 8080/8085 CPU Diagnostics、バージョン 1.0
- Diagnostics II、バージョン 1.2、Supersoft Associates による CPU テスト
- Ian Bartholomew と Frank Cringles による 8080/8085 CPU エクササイザー
Microcosm CPU Diag テスト スイートの ASM は次のとおりです。
