SYSTEMS AND METHODS FOR CACHE LINE REPLACEMENT

PROBLEM TO BE SOLVED: To provide a computer readable storage medium for determining a cache line to replace.SOLUTION: A system 300 includes a cache comprising a plurality of cache lines. When an instruction is executed by a processor, the system causes the processor to receive an index value included in an invalidate-cache-by-index instruction, a coded way value, and an output value of an incrementer 120 and, in response to the reception of the invalidate-cache-by-index instruction, to assign the index value as a value of an identifier 114. The value of the identifier indicates a cache line for replacement.
