Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Collaboration in a dual-processor system means: when one processor in the system needs to communicate with another processor, the processor as the data receiver needs to prepare the communication interface and be able to receive data normally; The sender's processor needs to determine that the receiver's communication interface is ready before sending data to ensure that the sent data will not be lost. When there is no need for data communication between two processors, it is considered that there is no connection between the two processors and they work independently of each other.

[0025] The technical problem to be solved by the embodiments of the present invention is to allow the communication interface to be closed to...

Abstract

The invention particularly discloses a mobile terminal power controller based on a dual processor comprises a hardware connection arranged between an application processor and a baseband processor and cooperative control modules respectively arranged on the application side and the baseband side, wherein the hardware connection is used for connecting signals between two processors; the cooperative control module is used for arranging signals on hardware connection when the cooperative control module side is a data sender, detecting signals on the hardware connection when the cooperative control module side is a data receiver. When the detected signals on the hardware connection are arousal or dormancy signals, the device informs the power management system at the side to adjust the power state, start or close the communication interface. The invention also discloses the power management method of the mobile terminal based on the dual processor. The example of the invention can reduce the power consumption at a standby state of the dual processor system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a power management device and method for a mobile terminal based on dual processors. Background technique [0002] With the development of mobile communication technology, the functions supported by mobile terminal products are becoming more and more complex and diverse, which makes mobile terminals designed based on a single processor encounter bottlenecks in processing capabilities. [0003] In order to overcome the problem of processing capability, mobile terminals based on dual-processor systems have been widely used. A dual-processor system includes an application processor and a baseband processor. The baseband processor is used to run the communication module. Application processors are used to run various application modules, including media, entertainment applications, and more. [0004] The use of dual processors can greatly improve the processing capability of th...
