Abstract
A clock control apparatus having a basic period clock and a plurality of clocks with different phases from the basic period clock by t/N period, is used with an information processing unit. The apparatus comprising a clock signal generating portion for generating pulses of the basic period clock, a cycle counter for counting the number of pulses of the basic period clock received from the clock signal generating portion when a start command is received and for outputting a cycle counter clock stop signal when the number of pulses becomes a predetermined count value, a control portion for outputting a basic enable period signal for controlling the basic period clock and a delay enable period signal for controlling the t/N period clocks by a flag and the cycle counter clock stop signal, the flag being assignable before the start command is received, a basic period clock enabling portion for receiving pulses of the basic period clock and for outputting the pulses of the basic period clock for a period designated by the basic enable period signal, and a t/N delay period clock enabling portion for generating pulses of the t/N period clocks and for outputting the pulses for a period designated by the delay enable period signal.
