CA 2037646

An information processing apparatus includes an arithmetic operation executing unit, a memory unit, a memory control unit, a resource managing unit, and an execution designating unit. The arithmetic operation executing unit executes an arithmetic operation on the basis of an instruction. The memory unit stores the arithmetic operation result from the arithmetic operation executing unit. The memory control unit has a buffer for temporarily storing data from the arithmetic operation executing unit and controls data transfer between the arithmetic operation executing unit and the memory unit. The resource managing unit manages use states of resources of the arithmetic operation executing unit. When an instruction is a data store instruction, the execution designating unit sends a buffer holding request to the memory control unit regardless of the resource state of the arithmetic operation executing unit. When a buffer holding response is supplied from the memory control unit, the execution designating unit designates execution of the data store instruction to the arithmetic operation executing unit and the memory control unit on the basis of management information from the resource managing unit.
