Abstract:
The present invention relates to an information processing apparatus equipped with a plurality of storage units and a plurality of system controllers sharing communication control on the plurality of storage units. For shortening the processing time needed for a memory access request, each of the plurality of system controllers includes a local snoop control unit for, when receiving the memory access request, retrieving target data on the memory access request from the storage unit, this system controller takes charge of, in parallel with transmission/reception processing on a retrieval instruction in a broadcast transmitting/receiving unit or processing in a global snoop control unit and a memory access control unit for fulfilling the memory access request when the target data is retrieved by the local snoop control unit and a predetermined condition reaches satisfaction.
