Terminal Hardware Control via CPU GPU Voltage Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of application programs on terminals increases, leading to slower operation speeds due to constant hardware performance, existing methods for controlling terminals by closing applications based on memory usage are limited in effectiveness, causing unnecessary resource consumption even in sleep or idle states.
Innovation Solution
A method and device that check hardware information such as CPU and GPU voltage and frequency to control the terminal, setting hardware operation modes (low power, normal, high power, and intelligent) based on this information to optimize performance and reduce resource consumption.

Engineering Contradiction Analysis
1Reliability
If application programs are closed according to memory usage to optimize terminal performance, then terminal performance is improved, but resource consumption is not effectively reduced and applications can restart quickly after closing
Solution Approach 1:
The patent changes the control parameter from memory usage to hardware operational state (CPU/GPU voltage and frequency). By monitoring hardware parameters rather than just memory usage, the system can identify when hardware is operating unnecessarily and control it accordingly, addressing both performance optimization and resource consumption reduction.
Solution Approach 2:
The patent implements a feedback mechanism where hardware information (voltage, frequency) is continuously monitored and fed back to the control module. This feedback loop enables dynamic adjustment of hardware operation modes based on actual usage patterns, preventing unnecessary resource consumption while maintaining terminal performance.
2Productivity
If hardware operates continuously to maintain terminal functionality, then terminal availability is maintained, but unnecessary resource consumption occurs during sleep or idle states
Solution Approach 1:
The patent applies dynamics by making hardware operation modes adjustable rather than fixed. The system can dynamically switch between different operational modes (e.g., high performance mode during active use, low power mode during idle states) based on real-time hardware information, optimizing the balance between availability and energy consumption.
Solution Approach 2:
The patent changes hardware operational parameters (voltage, frequency) based on usage state. During idle or sleep states, the system reduces hardware parameters to lower power consumption, while maintaining sufficient functionality for wake-up events, thus resolving the contradiction between availability and energy consumption.
