There is provided with a microprocessor control apparatus for controlling an operating speed of a microprocessor which executes a program including instruction codes, including: a state observing unit observing an execution state of the program at predetermined timings before execution of a deadline instruction code; prediction data of a remaining calculation amount required before execution of the deadline instruction code completes for each of predefined execution states; a predicted calculation amount acquiring unit acquiring a remaining calculation amount corresponding to an observed execution state as a remaining predicted calculation amount; a remaining time calculating unit calculating a remaining time until the deadline of the deadline instruction code; an operating speed calculating unit calculating a minimum operation speed of the microprocessor that is required to process the remaining predicted calculation amount within the remaining time; and a controlling unit controlling the microprocessor to operate at the minimum operating speed or higher.
