Information processing apparatus and information processing method

An information processing method for an information processing apparatus that includes

• first and second buses,
• a read/write command unit transmitting a read command or a write command to the first bus,
• a read command unit receiving a read command from the second bus, and
• a write command unit receiving a write command from the second bus, the method comprising:
• a command step of transmitting the read command and the write command to the read/write command unit based on the read command received by the read command unit and the write command received by the write command unit,
• wherein in the command step,
• a stand-by process is performed to stop transmitting the read command, and
• a re-arranging process is preformed to, while stopping transmitting the read command, change a transmission order of the read command and the write command so that the read/write command unit transmits the write command with higher priority than the read command.
