Abstract

The invention provides a method for realizing SoC fan control under a bootloader and a SoC using the method, which solves the problems in the prior art that the SoC fan control requires an additional fan controller, and the development cost of hardware and software is high. The method for realizing SoC fan control under the bootloader includes: the SoC executes the configuration of the fan speed register in the bootloader to drive the fan; the SoC judges whether the current speed of the fan in the fan speed sampling register reaches the set speed; if not, the SoC executes the bootloader The configuration of the fan speed register updated along the target direction; wherein, the target is to make the current speed of the fan equal to the set speed.

Description

technical field [0001] The invention relates to the technical field of SOC fan control, in particular to a method for realizing SoC fan control under a bootloader and an SoC applying the same. Background technique [0002] SoC fan heat dissipation is to use the fan to dissipate the heat on the SoC into the air to reduce the temperature of the SoC chip. The fan speed configuration and the actual fan speed will affect the heat dissipation effect of the SoC. [0003] In the prior art, the fan is controlled by a fan controller outside the SoC to realize heat dissipation. The problem with this is that on the one hand, an additional fan controller is required, which complicates the overall hardware design and increases the cost; on the other hand, there are various types of external fan controllers, and software developers need to refer to their data The manual is developed in a targeted manner, and the development cost is relatively high. [0004] Therefore, aiming at the above...
