Abstract
A semiconductor device capable of reducing power consumption is provided. A semiconductor device having a processor executing a plurality of tasks while switching the tasks in synchronization with a supplied operational clock signal includes: a processor-use-rate measuring unit configured to measure a use rate of the processor during a first term; and a frequency-dividing-value selecting circuit and a frequency dividing circuit configured to change a frequency of the operational clock signal supplied to the processor during a second term later than the first term on the basis of the use rate measured by the processor-use-rate measuring unit.
