摘要
A method and apparatus in a data processing system for protecting against a displacement of one type of cache line using a least recently used cache management process. A first member in a class of cache lines is selected as a substitute victim. The substitute victim is unselectable by the least-recently-used cache management process, and the substitute victim is associated with a second member in the class of cache lines. The substitute victim is replaced in response to a selection of the second member as a victim in response to a cache miss in the data processing system, wherein the second member remains in the class of cache lines.
