Estimating the term…
An apparatus includes: a processor core to execute an instruction; a first cache to retain data used by the processor core; and a second cache to be coupled to the first cache, wherein the second cache includes a data-retaining circuit to include storage areas to retain data, an information-retaining circuit to retain management information that includes first state information for indicating a state of data retained in the data-retaining circuit, a state-determining circuit to determine, based on the management information, whether requested data that is requested with a read request from the first cache is retained in the data-retaining circuit, and an eviction-processing circuit to, where the state-determining circuit determines the requested data not to be retained in the data-retaining circuit with no enough space in the storage areas to store the requested data, evict data from the storage areas without issuing an eviction request based on the read request.
An operation-processing device comprising:
An information processing apparatus comprising:
A control method for an operation processing device including a processor core configured to execute an instruction, a first cache configured to retain data used by the processor core, and a second cache configured to be connected to the first cache and to include a data-retaining circuit configured to include storage areas to retain data and a first information-retaining circuit configured to retain first management information that includes first state information indicating a state of data retained in the data-retaining circuit, the method comprising:
