Computational processing device including request holding units each provided for each type of commands, information processing device including request holding units each provided for each type of commands, and method of controlling information processing device

Abstract

A computational processing device includes: a computational-processor that outputs access requests to a storage device; a plurality of request-holding-units that respectively hold access requests output by the computational processor according to individual access types, the access types being types of access requests; an arbitration-unit that arbitrates access requests held in the plurality of request holding units; a buffer-unit that includes a plurality of entries that hold data; and a buffer-controller that causes one of the plurality of entries to hold data output by the storage device in response to an access request arbitrated by the arbitration unit, on the basis of a result of comparing, for each access type, a count value that counts, for each access type, the number of entries holding data from among the plurality of entries against a maximum value for the number of entries made to hold data for each access type.
