Abstract
A cache memory has a set associative scheme and includes a plurality of ways made up of entries, each entry holding data and a tag; a first holding unit holds, for each way, a priority attribute that indicates a type of data to be preferentially stored in that way; a second holding unit, included in a first way among the ways, holds, for each entry of the first way, a data attribute that indicates a type of data held in that entry; and a control unit replaces control on the entries by prioritizing a way whose priority attribute held by the first holding unit matches a data attribute outputted from a processor, wherein the control unit is further operable to store data into the entry of the way other than the first way.
