Abstract:
A data transfer apparatus includes: a first port and a second port that communicate data; a memory unit that stores the data; and a securing unit that secures, when a first time period starting from transmission of data up to reception of a response to transmitted data at the first port is longer than a second time period starting from transmission of data up to reception of a response to transmitted data at the second port, a first memory space that is used in data transfer in the first port so as for the first memory space to have a larger size than a size of a second memory space used in data transfer in the second port.
