From the project
BuntanPCはCPU・OS・言語処理系を手作りするプロジェクトです
最終的に BuntanPC で文書作成や Web 閲覧、ロボット制御、プログラミングなどをしたいです。
開発は当面パソコン上で行い、ビルド済みプログラムを転送して実行しますが、 最終的には BuntanPC 上で BuntanPC 向けのアプリを開発したいです。
PC は Pocket Computer もしくは Personal Computer の略です。 最初はきっとポケコン的な見た目や機能になると思います。 最終的にパソコンが作れたら楽しいですね。
当面は CPU と OS は BuntanPC Board で動かし、コンパイラ等の言語処理系はパソコン上で動かすことを想定しています。
