An apparatus and method for performing the dynamic frequency control of a central processing unit (CPU). The apparatus for performing the dynamic frequency control of a central processing unit (CPU) includes a frequency setting unit, a latency measurement unit, a frequency adjustment unit, and a control unit. The frequency setting unit sets optimum frequency using the measured amount of load. The latency measurement unit measures scheduler execution information. The frequency adjustment unit adjusts the optimum frequency using the scheduler execution information. The control unit incorporates the adjusted optimum frequency into a CPU.
