<p>A reference value is set and by means of a count value reaching the reference value a first reference signal and a second reference signal are generated by a first reference signal generation unit and a second reference signal generation unit. The generated first reference signal is received and a specified process is executed. The first reference signal is received and a restart is performed. An overhead until the specified process is executed is measured with the point in time of the restart as the starting point. A count value is acquired said count value being for the point in time at which the specified process is executed after the overhead has elapsed. When the acquired count value is different from the overhead value an assessment is made that the first reference signal and the second reference signal are not synchronous. A synchronization correction value is determined by subtracting the count value from the overhead value. A value obtained by subtracting the determined synchronization correction value from the reference value is set as a provisional reference value in the second reference signal generation unit.</p> |
