Abstract: A transfer-indication storage unit indicates an address and a data length of data to be transferred by a DMA circuit. An expected value table refers to a transfer indication of the transfer-indication storage unit and stores therein expected values of the address and the data length of the data to be transferred. A transfer-monitoring unit retrieves tag data and a data length of data in a bus. Based on the data length and the tag data notified by the transfer-monitoring unit, a table updating unit updates a start address and the data length in the expected value table. A determining unit determines whether the start address, corresponding to the DMA circuit after data transfer, matches with an end address, and further determines whether the data length has become zero.
