Power throttle mechanism with temperature sensing and activity feedback

摘要

Integrated circuit devices, methods, and other embodiments associated with power throttling with temperature sensing and activity feedback are described. In one embodiment, an integrated circuit device includes temperature sensing logic, activity sensing logic, comparison logic, and signal logic. The temperature sensing logic is configured to output a temperature signal indicative of a temperature of a selected region of the device. The activity sensing logic is configured to output an activity signal indicative of a level of activity of a selected device function. The mode selection logic is configured to select the temperature signal or the activity signal. The comparison logic is configured to compare the selected signal to a series of threshold levels and output a comparison result. The signal logic is configured to generate a throttle signal based on the comparison result. The throttle signal is used to control a frequency of operation of a selected device component.
