Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal throttling techniques for processing devices, which modulate the CPU to prevent overheating, result in disproportionate performance degradation and underutilization of resources, especially in devices where the CPU contributes a small fraction of the overall thermal output.
Innovation Solution
A method and system for thermal management that determines if a die temperature exceeds a threshold, selectively implements thermal reduction processes on peripheral components before the CPU, using a thermal diode and thermal throttling module to manage thermal output, prioritizing peripheral components based on criticality and thermal output, and adjusting operational modes to reduce thermal energy without degrading performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the CPU is throttled to reduce thermal output, then the temperature of the processing device is reduced, but the overall performance of the processing device is severely degraded
Solution Approach 1:
The patent segments the processing device into distinct components (CPU and peripheral components) with separate thermal throttling controls. The thermal throttling module can selectively throttle peripheral components while maintaining CPU performance, or throttle the CPU as a last resort. This segmentation allows targeted thermal management that reduces overall thermal output without severely degrading overall processing performance.
Solution Approach 2:
The patent implements local quality by applying different throttling strategies to different components based on their thermal contribution and performance criticality. Peripheral components that contribute significantly to thermal output but are less critical to overall performance are throttled first, while the CPU maintains full performance until necessary. This localized approach optimizes the balance between thermal reduction and performance maintenance.
2Temperature
If the CPU performance is reduced to manage thermal output, then thermal parameters are normalized, but processing resources are underutilized
Solution Approach 1:
The patent implements preliminary action by establishing a hierarchy of throttling targets before thermal crisis occurs. The system is pre-configured to throttle peripheral components first (such as graphics processors, audio processors, or other co-processors) before considering CPU throttling. This preliminary arrangement ensures that when thermal management is needed, the most thermal-contributing but least performance-critical components are reduced first, preserving CPU resource utilization.
Solution Approach 2:
The patent applies dynamics by making the throttling strategy adaptive and changeable based on real-time conditions. The thermal throttling module dynamically adjusts which components are throttled and by how much, based on current thermal readings, component thermal contributions, and performance requirements. This dynamic approach allows the system to maintain optimal resource utilization while managing thermal parameters.
3Reliability
If CPU throttling is applied whenever temperature approaches maximum limit, then thermal safety is ensured, but performance degradation is disproportionate to thermal reduction
Solution Approach 1:
The patent segments the thermal management approach into component-specific throttling zones. Instead of a monolithic CPU-throttle-all approach, the system identifies and throttles peripheral components that contribute disproportionately to thermal output. This segmentation enables more efficient thermal reduction per unit of performance sacrifice, as peripheral components often have higher thermal density relative to their performance contribution.
Solution Approach 2:
The patent changes the operational parameters of peripheral components (such as clock frequency, voltage, or operational mode) to reduce their thermal output while maintaining acceptable performance levels. By adjusting these parameters selectively on peripheral components rather than the CPU, the system achieves better thermal reduction efficiency with less impact on overall processing performance.

AI summary
Whether a temperature of a portion of a die of an integrated circuit device having a central processing device and one or more peripheral components has exceeded a first temperature threshold is determined. In response to determining that the temperature of the portion of the die has exceeded the first temperature threshold, a first thermal reduction process for a first peripheral component of the one or more peripheral components is selected and the first thermal reduction process for the first peripheral component is implemented.
