OPERATION PROCESSING DEVICE AND METHOD FOR CONTROLLING OPERATION PROCESSING DEVICE

摘要

An operation processing device including: processors, first cache corresponding to each processors; and a second cache shared by the processors, wherein the second cache includes; a data retaining unit that retains data, a first information retaining unit that retains first management information of data in the first cache, a second information retaining unit that retains second management information of data in the data retaining unit, a classifying unit that classifies a request performed by referencing the first management information and not referencing the second management information as a first type request and classifies a request performed by referencing the second management information as a second type request, a second processing unit that references the second management information to perform the second type request, and a first processing unit that references the first management information and does not reference the second management information to perform the first type request.

1. An operation processing device comprising:
a plurality of processors that executes instructions; a plurality of first cache memories that is provided in correspondence with the plurality of processors and retains data; and a second cache memory that is shared by the plurality of processors and is coupled to the plurality of first cache memories, wherein the second cache memory includes a data retaining unit that retains data, a first information retaining unit that retains first management information for management of data retained in the plurality of first cache memories, a second information retaining unit that retains second management information for management of data retained in the data retaining unit, a classifying unit that classifies a request for a process, of a plurality of process requests including a read request from any of the plurality of first cache memories, performed by referencing the first management information and not referencing the second management information as a first type process request and classifies a request for a process performed by referencing the second management information as a second type process request, a second processing unit that references the second management information to perform a process which is based on the second type process request received from the classifying unit, and a first processing unit that references the first management information and does not reference the second management information to perform a process which is based on the first type process request received from the classifying unit, and is operable in parallel with the second processing unit.
