Method and apparatus for generating a clock signal and for controlling a clock frequency using the same

摘要

A method and a device for generating a clock signal determine a number of pulses to be discarded from each predetermined cycle of a reference clock signal in order to obtain, on average, a target frequency. A masking pattern is created for discarding the number of pulses to be discarded from each predetermined cycle of the reference clock signal. The clock signal, which includes the target frequency, is generated by discarding the number of pulses from the reference clock signal using the masking pattern.

1. A method of controlling a clock frequency, the method comprising:
generating a clock signal for an application having, on average, a target frequency from a reference clock signal; calculating a data processing progress percentage of processing data using the clock signal; determining a difference between the calculated data processing progress percentage and a target progress percentage; and changing the target frequency of the clock signal based on the determined difference.
