A dynamic clock control methodology for low-power SoC is designed and implemented. The dynamic clock control methodology is comprised of seff-adaptive dynamic frequency regulation, clock gating and multi-mode switch. The methodology is applied to a low-power microcontroller which is based on openMSP430 microprocessor. The simulation results show that the power consumption of the microeontroller is reduced effectively without any efficiency and performance degradation
