Abstract

The invention discloses a multi-processor power management system. Multiple processors include a main processor and auxiliary processors; the multi-processor power management system comprises software monitoring modules, processing modules and power control modules; the software monitoring modules are used for monitoring the service condition of each auxiliary processor in real time; the processing modules are used for judging whether each auxiliary processor is in an idle or overload state; the power control modules are used for controlling on-off of a power supply of each auxiliary processor; according to the auxiliary processor service conditions acquired by the software monitoring modules in real time, when the auxiliary processors are in the idle state, the processing modules perform system restart on the auxiliary processors, and when the auxiliary processors are in the overload state, the processing modules shut off the power supplies of the auxiliary processors through the power control modules. The service conditions of the auxiliary processors are monitored by software, and the power states of the auxiliary processors are controlled according to the service conditions, so that the technical effects of actual shut off of the power supplies of the auxiliary processors and reduction of emitted heat are realized.

Description

technical field [0001] The invention relates to a multiprocessor power management system, method and intelligent terminal. Background technique [0002] Now more and more handheld terminal products, including MIFI, smartphones, smart routers, smart charging treasures, etc., have begun to use dual processors (hereinafter referred to as "CPU") in order to ensure higher performance and computing speed. Even three CPUs. [0003] However, the following problems are also more obvious. The number of CPUs increases, the power consumption of the motherboard increases, the corresponding power consumption increases, and the heat generation increases. For terminal products with independent shell designs, heat dissipation has become an urgent problem to be solved. . The way to solve this problem in the prior art is to strive for heat dissipation space as much as possible in the structure. Since the current circuit design is more and more inclined to integration and high-quality product...
