INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM AND PHASE ADJUSTING METHOD

摘要

An information processing apparatus configured to adjust a phase relation between a data signal and a strobe signal includes a processor and memory. The memory stores instructions for causing the processor to execute identifying, for each of a plurality of candidates for reference values used to perform a determination regarding a value of the data signal, at least one phase difference between the data signal and the strobe signal for successfully acquiring the data signal according to the strobe signal, determining a reference value of the plurality of candidates for which a period for successfully acquiring the data signal is longer than periods for any other candidates based on the identified phase difference for each candidate, and adjusting the phase relation between the data signal and the strobe signal based on the period for the determined reference value.

1. An information processing apparatus configured to adjust a phase relation between a data signal and a strobe signal, the information processing apparatus comprising:
a processor; and memory storing instructions for causing the processor to execute:
identifying, for each of a plurality of candidates for reference values used to perform a determination regarding a value of the data signal, at least one phase difference between the data signal and the strobe signal for successfully acquiring the data signal according to the strobe signal;determining a reference value of the plurality of candidates for which a period for successfully acquiring the data signal is longer than periods for any other candidates based on the identified phase difference for each candidate; andadjusting the phase relation between the data signal and the strobe signal based on the period for the determined reference value.
