Terminal Wake-Up Hierarchy for Low-Power Peripheral Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overall standby capability of electronic devices is affected because when a main controller in a terminal device is woken up, other main controllers and peripheral apparatuses are also woken up, leading to increased power consumption and reduced standby time.
Innovation Solution
A hierarchical management method and system for terminal devices, where the control system wakes up only the necessary peripheral apparatuses based on the received wake-up signal and data load, grading its operation mode from ultra-low-frequency to full-speed accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a universal self-registration mechanism is used to wake up the main controller, then the device can respond to wake-up signals, but all peripheral apparatuses are woken up unnecessarily, increasing power consumption
Solution Approach 1:
The system segments the wake-up process into multiple levels: first waking up only the necessary control system based on the wake-up signal type, then selectively waking up peripheral apparatuses based on graded operation modes. This segmentation prevents unnecessary wake-up of all components, reducing power consumption while maintaining reliable wake-up response.
Solution Approach 2:
The system applies partial action by waking up only the minimum necessary components based on the operation mode. Instead of waking up all peripheral apparatuses (excessive action), the system wakes up only those required for the current operation mode (partial action), optimizing power consumption while ensuring adequate response capability.
2Adaptability or versatility
If all peripheral apparatuses are woken up when a control system wakes up, then complete system functionality is available, but standby capability is reduced due to accumulated power consumption
Solution Approach 1:
The system dynamically adjusts the wake-up scope based on the operation mode. Different operation modes (first, second, third modes) correspond to different levels of peripheral apparatus wake-up. This dynamic adjustment allows the system to balance functionality and standby time by selecting appropriate operation modes based on actual needs, rather than using a fixed all-or-nothing approach.
Solution Approach 2:
The system applies local quality by differentiating the wake-up state of different peripheral apparatuses. Instead of treating all peripherals uniformly, the system selectively wakes up specific peripherals based on which control system woke up and the determined operation mode. This localized approach ensures adequate functionality while minimizing unnecessary wake-ups, thereby extending standby time.
3Speed
If the main controller enters normal frequency operation mode immediately upon wake-up, then processing speed is maximized, but power consumption increases unnecessarily for light data loads
Solution Approach 1:
The system changes operational parameters (frequency mode and peripheral wake-up state) based on the determined operation mode. Instead of always operating at normal frequency with all peripherals awake, the system adjusts parameters to match the actual data load requirements, achieving an optimal balance between processing speed and power consumption.

AI summary
Disclosed is a hierarchical management method and system for a terminal device. The terminal device comprises at least one control system, and at least one peripheral apparatus, which is connected to the control system. In the method, when a terminal device receives a wake-up signal during dormancy, a control system corresponding to the wake-up signal is woken up, and the control system in a wake-up state grades an operation mode of the control system according to a data load; and according to the operation mode, a peripheral apparatus that needs to perform data processing is woken up.
