Each of the first plurality of entries comprises a value (ADDRESS TAG) for corresponding the entry to a corresponding first plurality of data fetching instructions. Further, each of the first plurality of entries further comprises a value (POINTER A) for indicating a corresponding predicted target data address. Each of the second plurality of entries also comprises a value (ADDRESS TAG) for corresponding each of the second plurality of entries to a corresponding second plurality of data fetching instructions. However, each of the second plurality of data fetching instructions is of a type for which it is undesirable to issue a prefetch request.
