Abstract

The invention discloses a control method and a device of a power circuit and electronic equipment. The method is applied to the electronic equipment provided with two processors, wherein a first processor is provided with a sub-processor with the same function as the second processor, and the two processors are respectively connected with a core power supply circuit for basic power supply and share the other group of power supply circuits. The method comprises the following steps: detecting whether the second processor is working, if so, supplying the shared power circuit to the second processor for use, and if not, supplying the shared power circuit to the sub-processor of the first processor for use. Therefore, the use efficiency of the system power supply can be greatly improved. In addition, due to the fact that one set of power circuits can be shared, the wiring area can be greatly reduced, the manufacturing cost is saved, and the requirement for miniaturization can be better met.

Description

technical field [0001] The present application relates to the field of power circuits, in particular to a control method, device and electronic equipment for a power circuit. Background technique [0002] In traditional power architectures, multiple independent power circuits are usually provided for multiple processors. But in practice, since some processors may have overlapping functions or conflicting functions, they do not need to run at the same time. [0003] In the above case, if each processor uses an independent power supply circuit, it will not only occupy a larger area, but also reduce the power supply efficiency of the power supply, and cannot make full use of electric energy. Contents of the invention [0004] The applicant creatively provides a control method, device and electronic equipment for a power supply circuit. [0005] According to the first aspect of the embodiment of the present application, a method for controlling a power supply circuit is prov...
