ABSTRACT:
A method for reducing an importance level of a line in a memory of a cache. An instruction is provided to the cache, the instruction indicating that the line is a candidate for replacement. The importance level of the line may then be reduced based on the instruction. The method may increase cache hit rate and, hence, microprocessor performance.
