ALU制御回路回路はALUを操作するための制御信号生成し，また演算結果からフラグを生成する機能を持っています。 #### ALU本体 aluc
最新バージョン : v1.1 *** ### レジスタファイル レジスタファイルとは，プロセッサ内で一時的に記憶するレジスタと呼ばれる回路を複数集積したものです。NLP-16Aでは16bitのデータを記憶可能なレジスタを16本持っています。
汎用レジスタは5本で，残りのレジスタは何らかの役割を持ち，単純な記憶以外の動作も行うことがあります。
最新バージョン : v1.2 *** ### 入出力 NLP-16Aは16 bit x 64 kwordの1つの入出力ポートを持っています。 内部的にはレジスタの一つとしてアクセス可能な構造になっています。
主記憶及び外部デバイスとの接続に使用されます。 #### 外部バス制御 Busterminator
