Abstract:
A controller is provided that controls data transfer between a processor and a data transfer device and that includes: a storage unit that stores first data outputted from the processor; a determination unit that compares control information of the first data and control information of second data received from the processor after the first data, and determines whether a first case in which the first data and the second data include the same data body holds according to a result of the comparison; a management unit that stores a portion of the control information of the second data as duplicate information associated with the first data in the first case, and stores the second data in the storage unit in a second case other than the first case; and a control unit that controls output of data stored in the storage unit to the data transfer device.
