Abstract
An HW arithmetic unit executes a predetermined arithmetic operation. An arithmetic-mode determining unit determines, based on an attribute or a content of data relating to processing that has requested the arithmetic operation, either a synchronous mode that executes the processing after waiting for completion of the arithmetic operation by an arithmetic circuit or an asynchronous mode that executes the processing without waiting for completion of the arithmetic operation by the arithmetic circuit, as an execution mode of the arithmetic operation. An arithmetic-process control unit controls the arithmetic operation by the arithmetic circuit according to the determined execution mode.
