Abstract:
If data received by the an information processing apparatus from an external device is delayed by one cycle or more with respect to a clock of the information processing apparatus, the information processing apparatus may require an additional process for adjusting a data latch timing.Delay information indicating a relationship between a calibration pattern to be received and an amount of cycle delay is stored in advance. Thus, the time required for detecting an amount of cycle delay, which is equivalent to the amount by which a signal for controlling a data latch mechanism in the information processing apparatus to stop its operation is delayed, can be reduced.
