Abstract: A thermal control system for an integrated circuit in an electronic device includes a sensing unit, a calculating unit, and a control unit. The sensing unit is for providing a first temperature signal by sensing the temperature of the integrated circuit and providing a second temperature signal by sensing the temperature of a component of the electronic device. The calculating unit computes a target temperature value of the integrated circuit according to the second temperature signal. The control unit adjusts target setting for the integrated circuit according to the target temperature value and the first temperature signal.

Abstract: Methods and apparatus are provided for adjusting the power limit based on multiple factors including the current temperature, the previous temperature, and the target temperature. In one novel aspect, the device obtains the total power limit based on the base power and the delta power. The base power is set to be the current power if the temperature-jump is higher than a temperature-jump threshold, otherwise, is set to be the previous power limit. The delta power equals to the weighted conversion sum of the temperature jump and the temperature margin, which is the temperature difference between the current temperature and the target temperature. In another novel aspect, the device calculates one or more component power limit for each corresponding component power source of the device based on the total power limit. The device adjusts power settings for each corresponding component power source based on the component power limit.
Abstract translation: 提供了用于基于包括当前温度，先前温度和目标温度的多个因素来调节功率极限的方法和装置。 在一个新颖的方面，设备基于基本功率和增量功率获得总功率限制。 如果温度跳变高于温度跳变阈值，则基本功率设置为当前功率，否则设置为先前的功率限制。 δ功率等于温度跳变和温度裕度的加权转换和，即当前温度与目标温度之间的温差。 在另一个新颖的方面，设备基于总功率限制来计算设备的每个相应组件功率源的一个或多个组件功率限制。 该设备根据组件功率限制调整每个相应组件电源的电源设置。
