一种电压调整方法及相应的HPM、芯片和芯片系统
摘要：
本申请公开了一种电压调整方法及相应的HPM、芯片和芯片系统。其中，所述方法用于调整芯片的工作电压，包括AVS模块和至少一个HPM，所述方法包括：所述AVS模块向所述HPM输出时钟信号；所述HPM根据所述时钟信号产生相应的脉冲信号，并至少对所述脉冲信号进行第一延时，以得到第一实际输出值，对所述脉冲信号进行第二延时，以得到第二实际输出值；所述AVS模块至少根据所述第一、第二实际输出值的权重，对所述第一、第二实际输出值进行拟合，获得拟合输出值，并通过比较所述拟合输出值与预设的基准值的大小，确定是否调整所述芯片的工作电压。通过上述方式，本申请能够使芯片正常工作的前提下有效降低芯片功耗。
摘要（英）：

The application discloses a voltage regulation method, and a corresponding HPM, chip, and chip system. The method is used to regulate a working voltage of the chip, which includes an AVS module and at least one HPM. The method includes: outputting, by the AVS module, a clock signal to the HPM; generating, by the HPM, a corresponding pulse signal according to the clock signal and at least performing first delaying for the pulse signal to acquire a first actual output value and performing second delaying for the pulse signal to acquire a second actual output value; and fitting, by the AVS module, the first and second actual output values at least according to weights of the first and second actual output values to acquire a fitting output value and determine, by comparing the fitting output value with a predetermined reference value, whether to regulate the working voltage of the chip.
