Processor Wake-Up Frequency Control for Lower Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Processor power consumption is unnecessarily high when systems are in a normal operating state due to processors being kept in a wake-up mode to handle sensor processing events, leading to increased energy usage.
Innovation Solution
A processor power consumption control method that adjusts the wake-up frequency based on the current operating scenario by using an AI processor with a wake-up mode and a sleep mode, determining the operating scenario through an acquisition unit, and configuring data relevant to the wake-up frequency based on operating parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor is kept in a wake-up mode to handle sensor processing events, then the system reliability is improved, but the power consumption increases
Solution Approach 1:
The processor dynamically adjusts its operating state between wake-up mode and sleep mode based on the actual system operating scenario. The controller determines whether the system is in a static or dynamic state and accordingly configures the processor to be in wake-up or sleep mode, making the system adaptable to different operational requirements while optimizing power consumption.
Solution Approach 2:
The system changes the operational parameters of the processor by adjusting its power state (wake-up frequency, sleep duration) based on the detected operating scenario. When the system is in a static scenario, the processor enters sleep mode with reduced power consumption; when in a dynamic scenario, it transitions to wake-up mode to handle sensor events, thus optimizing the balance between reliability and energy usage.
2Productivity
If the processor is kept in a wake-up mode to ensure smooth sensor processing, then the processing capability is improved, but the energy efficiency deteriorates
Solution Approach 1:
The processor operates in periodic cycles, alternating between wake-up mode and sleep mode based on the system's operating scenario. During static scenarios, the processor remains in sleep mode for extended periods, periodically waking up only when necessary. This periodic operation pattern maintains processing capability when needed while significantly reducing energy consumption during idle periods.
Solution Approach 2:
The system includes a controller that automatically monitors the operating scenario and makes decisions about processor state transitions without external intervention. The controller self-adjusts the processor's wake-up frequency and sleep duration based on detected system states, enabling the system to autonomously optimize its energy efficiency while maintaining necessary processing capabilities.

AI summary
A processor power consumption control method includes responding to a processor being woken up, obtaining an operating parameter of a system by the processor when the system is in an operating state, determining a current operating scenario of the system based on the operating parameter, and configuring data related to a wake-up frequency of the processor based on the current operating scenario. Different the wake-up scenarios correspond to different wake-up frequencies of the processor.
