Solution Overview

Problem

Existing systems face overheating issues during turbo boost mode due to the prioritization of CPU overclocking over temperature protection, leading to potential system crashes or damage, with current solutions either sacrificing performance or increasing costs by lowering power limits or replacing components.

Innovation Solution

A method and system for dynamically tuning thermal design power by sending power tuning signals to the BIOS to adjust the real-time operating power of the CPU based on temperature thresholds, switching between PL1 and PL2 power levels to maintain system stability and performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the CPU operates in turbo boost mode with high power limits, then system performance is improved, but temperature protection mechanisms cannot affect the operation and electronic components may overheat

Engineering Contradiction:

ImproveCPU performanceVSAvoidtemperature

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic adjustment of turbo boost parameters (power limits, Tau parameters, frequency) based on real-time temperature conditions. The system transitions from static fixed parameters to dynamic adjustable parameters, allowing the CPU to operate at high performance when temperatures are acceptable and automatically reduce power when temperature thresholds are approached, resolving the contradiction between maintaining high performance and preventing overheating.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (power limits, Tau parameters, frequency) based on temperature conditions. By monitoring temperature and adjusting these parameters dynamically, the system can maintain optimal performance within safe thermal boundaries, allowing turbo boost operation without compromising temperature protection.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the upper power limit of the turbo boost mode is lowered to prevent overheating, then temperature protection is improved, but system performance is sacrificed

Engineering Contradiction:

Improvetemperature protectionVSAvoidsystem performance

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

Instead of using a fixed lower power limit, the system dynamically adjusts power limits based on real-time temperature monitoring. This allows the system to maintain high performance (135W) when temperatures are safe and automatically reduce power when approaching thermal thresholds, eliminating the need to permanently sacrifice performance for temperature protection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements a feedback mechanism where temperature sensors continuously monitor thermal conditions and feed this information back to the controller, which then adjusts turbo boost parameters accordingly. This closed-loop control allows the system to maintain high performance while automatically responding to temperature conditions, rather than using a conservative fixed power limit.

Inventive Principle:

Principle #23Feedback

3Object-affected harmful factors

If electronic components with higher temperature tolerance are used to withstand turbo boost heat, then temperature resistance is improved, but system cost increases

Solution Approach 1:

The patent implements dynamic control of turbo boost parameters based on real-time temperature monitoring, allowing the system to operate at full performance when thermal conditions permit and automatically reduce power when approaching thermal thresholds. This software-based thermal management eliminates the need for expensive high-temperature-tolerance components by preventing overheating through intelligent parameter adjustment.

AI summary

A method and a system for dynamically tuning thermal design power and a non-transitory computer-readable storage medium are described. The system is configured to dynamically tune turbo boost mode operation parameters of a central processing unit (CPU), independent of related settings of a turbo boost operation state of the CPU. In an embodiment, a controller is configured to send a power tuning signal to a basic input/output system (BIOS) to directly intervene and tune a real-time operating power of the CPU.
