摘　　要：设备温度的升高会影响芯片的稳定性和性能,而目前温度控制的方法基本都是通过控制CPU的频率电压,从而降低CPU的功耗来控制整个设备的温度,而忽略了其他功耗比较大的模块(比如GPU、DDR)。笔者提出利用Linux的温度控制框架,采用step-wise的温控策略,同时控制CPU、GPU、DDR的频率电压来降低功耗,来更有效地进行温度控制以及性能分配。Increased device temperature will affect the stability and performance of the chip,and the method of temperature control through basic frequency voltage control CPU,thereby reducing the power consumption of the CPU to control the temperature of the device,while ignoring the other relatively large power modules(such as GPU,DDR).The author proposes to use the temperature control framework of Linux,adopt the temperature control strategy of step-wise,and control the frequency voltage of CPU,GPU and DDR to reduce power consumption,and to control temperature and performance more effectively.
