Abstract
An operation clock generation circuit performs calculation on the basis of the frequency errors of a fundamental clock and the clock pulses of the fundamental clock, and generates an operation clock obtained by correcting the frequency errors at first intervals. A correction clock generation circuit converts a lower-bit value that is a value represented by the bits lower than the predefined bit used for judging the change of the state of the operation clock into a count number of the clock pulses of a second clock whose frequency is higher than that of the operation clock, generates a correction clock obtained by correcting the operation clock on the basis of a time required for counting the count number of the clock pulses and the clock pulses of the operation clock.
