Abstract
【解決手段】フラッシュメモリ1がマイクロプロセッサ3とペースを保つために専用フラッシュ・バス2がフラッシュメモリ1をマイクロプロセッサ3へつなげる。前記フラッシュ・バス2がマイクロプロセッサのデータ・バス8の幅nより大きな幅mを有する。好ましくは、幅mは幅nの複数倍である。多数の中間記憶装置4は、幅変換の機能をもたらすためにフラッシュ・バス2をマイクロプロセッサ3のデータ・バス8に接続する。これらの中間記憶装置4は、付加的なタグ記憶装置5とともにマイクロプロセッサのデータ要求に対してキャッシュとして作用しICの潜在的速度を向上させる。
【選択図】図1
Description
1. 1の手段は、組み込まれたフラッシュメモリのデータワード幅をそのアクセス時間の動作を補正するために増加させることである。
2. 他の手段は、データ・キャッシュを、特に、中間データ記憶装置を単一または複数のデータ・ライン・キャッシュとして使用することによって、配設することである。
Claims (1)
- 少なくとも1つのマイクロプロセッサおよび少なくとも1つのメモリを備えた集積回路であって、
前記メモリは、前記マイクロプロセッサへ専用のフラッシュ・バスによって機能的に結合された不揮発性またはフラッシュメモリであり、
前記専用のフラッシュ・バスは、第1の幅mを有し、第1の幅mは前記マイクロプロセッサまたはそのデータ・バスのそれぞれの第2の幅n、特に第2の幅nのある倍数よりも大きい集積回路。
