Abstract: The CPU includes a plurality of CPU cores. The temperature determination unit determines whether or not the temperature indicated by the acquired temperature information is equal to or higher than a threshold value. When it is determined that the temperature indicated by the temperature data is equal to or higher than the threshold value, the thermal generation control unit performs thermal generation control on the CPU. The group data includes high-priority group information specifying a CPU core of a first group to which execute of a high-priority application is allocated in the CPU, and low-priority group information specifying a CPU core of a low-priority group to which execution of a low-priority application is allocated in the CPU. Based on the group data, the control target determining unit determines a CPU core to be subjected to thermal generation control from among the CPU cores of the low priority group.

Abstract: A semiconductor device is provided which can suppress heating while assigning performances to a plurality of modules whose heat generations are controlled while considering usage conditions of the plurality of modules.

Abstract: An operating condition is controlled from viewpoints both processing capacity and power consumption. A CPU 11 includes, for example, a plurality of CPU cores 11a to 11d, and configured to such that an operating condition can be varied. A performance table 26 is a table representing a relationship between the operating condition of the CPU 11 and the processing capacity of the CPU 11. A power consumption table 27 is a table representing a relationship between the operating condition of the CPU 11 and power consumption. An operation control unit 22 controls the operating condition of the CPU 11 referring to the performance table 26 and the power consumption table 27.
