INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD

摘要

An information processing apparatus having first and second buses, includes: 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; a write command unit receiving a write command from the second bus; and a command unit transmit the read command and the write command to the read/write command unit based on the read and write commands received by the read command unit and the write command unit.;Further, the command unit stops transmitting the read command, and, while stopping transmission of the read command, change a transmission order of the read and the write commands so that the read/write command unit transmits the write command with higher priority than the read command.

1. An information processing apparatus including first and second buses, comprising:
a read/write command unit configured to transmit a read command or a write command to the first bus; a read command unit configured to receive a read command from the second bus; a write command unit configured to receive a write command from the second bus; and a command unit configured to transmit 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 the command unit is configured to
perform a stand-by process to stop transmitting the read command, andperform a re-arranging process 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.
