ABSTRACT:
A processor capable of executing prefetching instructions containing hint fields is provided. The hint fields contain a first portion which enables the selection of a destination indicator for refill operations, and a second portion which identifies a destination. The portion of the hint field identifying a destination may be applied to consistently direct streamed and retained data to select portions of a cache. As a result, one type of data (e.g., retained) is lees likely to be replaced by another type of data (e.g., streamed) and vice versa.
