The invention provides a chip overheating automatic protection method and device. The method comprises the steps of: receiving the output values of a plurality of temperature sensors which are located at different positions in a chip and each provided with a corresponding control threshold; when the output value of at least one temperature sensor is higher than the corresponding control threshold, generating an interrupt signal; judging the interrupt signal to generate a decision control result; and triggering a corresponding automatic control state machine according to the decision control result, and automatically adjusting the temperature of the chip. Hardware response and control can be quickly and effectively executed, the chip can be recovered to a normal temperature range in a short time, and various control strategies are provided to reduce the load of the chip. 本发明提供了一种芯片过热自动保护方法和装置，包括，接收多个温度传感器的输出值，所述多个温度传感器分别位于芯片内部的不同位置，并且每个温度传感器具有相应的控制阈值；当至少一个温度传感器的输出值高于所对应的控制阈值时，生成中断信号；对所述中断信号形成判决，产生决策控制结果；根据所述决策
