Abstract
An arithmetic processing device includes a core, and a first control circuit that controls a memory request issued by the processing core. The first control circuit includes a miss access control unit with input entries that assigns an input entry to the memory request to control a process of the memory request, and a control pipeline circuit that performs a cache hit determination and issues a memory request to the miss access control unit in a case of cache miss. The control pipeline circuit includes a speculative request control unit that issues a speculative memory request to the miss access control unit before the cache hit determination is performed, cancels the issued speculative memory request in a case of cache hit, and more suppresses issuing the speculative memory request when the number of input entries assigned to the canceled speculative memory request increases.
