Abstract
The present information processing apparatus, which receives and executes commands, monitors time-outs of commands with reliability, thereby making it possible to prevent a command initiator from detecting time-outs of the commands. The apparatus includes: a time stamp unit for storing, in a command buffer, a receiving time at which a command receiving unit received a command, in association with the command; and a read-out time-out detecting unit for detecting read-out time-out of a first buffered command in the command buffer, based on the receiving time of the first buffered command. If the read-out time-out detecting unit detects a read-out time-out, the command executing unit reads the command, for which the read-out time-out is detected, from the command buffer and executes the read-out command.
Claims19
An information processing apparatus, comprising:
- a command receiving unit for receiving a command;
- a command buffer of a first-in first-out type for temporarily storing therein the command received by said command receiving unit;
- a time stamp unit for storing, in said command buffer, a receiving time at which said command receiving unit received the command, in association with the command;
- a command executing unit for reading the command stored in said command buffer and executing the read-out command;
- and
- a read-out time-out detecting unit for detecting read-out time-out of a first buffered command in said command buffer, based on the receiving time of the first buffered command,
- said command executing unit, if said read-out time-out detecting unit detects a read-out time-out of the command, reading the command, for which the read-out time-out is detected, from said command buffer and executing the read-out command.
Dependencies are inferred from the claim text.
