Multi-Component Thermal Throttling for Sustained Processor Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices throttle their performance prematurely due to temperature constraints, with the processor's guaranteed temperature often being higher than other components, leading to unnecessary performance reduction.
Innovation Solution
An electronic device with temperature measurement units and a controller that adjusts the operating frequency based on reference temperatures for both the processor and other components, delaying throttling and maintaining performance by reducing frequency only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If throttling is performed based on the processor's guaranteed temperature, then the processor temperature is controlled within the guaranteed range, but the throttling occurs before other components reach their guaranteed temperatures, causing unnecessary performance reduction
Solution Approach 1:
The patent segments the temperature control system into multiple independent temperature monitoring channels, each dedicated to a specific component (processor, memory, display, etc.). Each channel has its own temperature sensor and control logic, allowing independent temperature management for each component based on its specific guaranteed temperature range. This segmentation enables the system to identify which specific component requires throttling rather than applying blanket throttling based solely on processor temperature.
Solution Approach 2:
The patent implements dynamic temperature control by continuously monitoring temperatures of multiple components and adjusting the operating frequency based on the real-time thermal state of each component. The system dynamically determines the appropriate frequency level by comparing current temperatures against guaranteed temperature ranges for each component, enabling adaptive performance optimization rather than static throttling policies.
2Temperature
If the operating frequency is reduced to control temperature, then the temperature remains within guaranteed ranges, but the operation performance is reduced
Solution Approach 1:
The patent applies local quality control by managing temperature and frequency settings for each component individually based on its specific thermal characteristics and guaranteed temperature range. Each component receives customized temperature control treatment rather than uniform control, allowing the system to maintain high performance for components that can tolerate higher temperatures while providing targeted cooling or frequency reduction only for components approaching their thermal limits.
Solution Approach 2:
The patent changes operating parameters (frequency levels) based on real-time temperature measurements and guaranteed temperature ranges. The system monitors temperature parameters and dynamically adjusts frequency parameters to maintain optimal operation, changing from static frequency settings to dynamic parameter adjustment based on thermal conditions of each specific component.

AI summary
An electronic device and method of operating an electronic device are provided. The electronic device includes a temperature measurement unit configured to measure a temperature of each of multiple components of the electronic device, and a controller configured to change, based on a first reference temperature, an operating frequency of the controller to a first operating frequency when a temperature of the controller, measured by the temperature measurement unit, reaches the first reference temperature and change, based on a third reference temperature that is lower than the first reference temperature, the operating frequency of the controller to a second operating frequency when a temperature of at least one component of the multiple components reaches a second reference temperature while the controller operates at the first operating frequency.
