ABSTRACT:
A mechanism using CH.sub.Loc (change-local) type information is used for data prefetch (D-prefetch) decision making. This information is stored in history tables H, there being one such table for each central processor (CP) at, for example, the buffer control element (BCE). For each line L, H[L] indicates the information for L in H. Two different types of histories may be kept at H:
