Smartphone frequency and voltage adjustable power management module based on multi-core architecture

Abstract

The invention belongs to an embedded mobile terminal device, in particular to a smartphone frequency and voltage adjustable power management module based on a multi-core architecture. The smartphone frequency and voltage adjustable power management module is mainly characterized by comprising an application service layer module, an intelligent power save policy, a PCP (Power Consumption Profile), a DVFS (Dynamic Voltage and Frequency Scanning) and independent hardware modules such as CPU, GPU, DDR memory, crystal oscillator and power amplifier, etc.; the application service layer realizes power save mode policy control configured based on a use habit and a use preference of a user, and realizes use of a control logic of a battery at maximum after self-learning modeling; the intelligent power save policy opens a management policy for configuring an intelligent power save mode by a terminal user; and the PCP adjusts a working voltage and a frequency of each hardware module in cooperation with the DVFS according to the management policy configured by the system, so as to achieve the purpose of optimizing the power consumption management of the system.

Description

technical field [0001] The invention belongs to embedded mobile terminal equipment, in particular to a frequency-adjustable and voltage-adjustable power supply management module for smart phones based on a multi-core architecture. Background technique [0002] With the rapid development of communication technology, multimedia technology and mobile Internet, the emergence of new multi-core hardware platforms, the 4G network's dependence on large data traffic, and the application of larger resolution screens to mobile phone products, the power consumption of mobile phones continues to rise. , As a result, the system standby time cannot meet the requirements. For today's powerful mobile phones, especially those with high-resolution large screens and 4-core or 8-core CPUs, the power consumption is already increasing at a multiple level of the single-core era, so users are experiencing a variety of colorful When performing business, there will naturally be phenomena such as insu...
