  • Semiconductor device, electronic device, and method for controlling semiconductor device
    Patent number: 9898068
    Abstract: A semiconductor device includes a CPU core, a frequency regulating circuit, and a frequency control circuit. The frequency regulating circuit includes a table. The frequency control circuit provides a clock to the CPU core. The CPU core outputs an operating state signal indicating an operating state of the CPU core. The frequency regulating circuit controls a frequency of the clock based on the table and the operating state signal. Thus it is possible to provide a semiconductor device that allows performance to follow a dynamically changing load.
