Abstract

A timing control apparatus includes an adder and a comparator. The adder adds unused time error in each of a plurality of periods to form a cumulative value, and the comparator compares the cumulative value to a reference value. The unused time error is computed during operation of a first clock, and a control signal is generated to switch from the first clock to a second clock based on an output of the comparator. The frequency of the first clock is greater than a frequency of the second clock.
