The paper presents a method of optimum control of throughput (OCT) of microprocessor (or other processing machine) with taking into account required efficiency, which is taken from operating system, and internal temperature. The optimum performance of integrated system is achieved by means of required efficiency control for safety i.e. low enough temperatures and temperature-based control utilizing thermal feedback for dangerous (high) internal temperatures. The latter control technique, which is obtained using dedicated Temperature-Controlled Oscillator (TCO), assures thermal reliability, i.e. ensures that semiconductor structure temperature do not exceed the critical value of this quantity. The presented method guarantees energy savings and against overheating. The optimum control of throughput of microprocessor is modeled and analyzed using Simulink.
