Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processor environments lack the ability to dynamically manage transitions between different processor core types, leading to inefficient resource allocation, inaccurate performance assessment, and suboptimal power management due to static power information and lack of core type awareness in task schedulers.
Innovation Solution

Engineering Contradiction Analysis
1Productivity
If a processor environment uses static power information and lacks core type awareness, then the system is simpler to implement, but resource allocation becomes inefficient and power management becomes suboptimal
Solution Approach 1:
The patent implements dynamic core type transition management that allows processor cores to transition between different core types (e.g., performance cores and efficiency cores) based on workload characteristics. This dynamic adaptation enables the system to optimize resource allocation and power management in real-time, resolving the contradiction between simplicity and efficiency by introducing controlled complexity only where needed for performance optimization.
Solution Approach 2:
The system changes operational parameters by dynamically adjusting core type assignments based on workload context. The processor management system monitors workload characteristics and modifies core type parameters accordingly, allowing the same physical core to operate in different modes (performance or efficiency) depending on requirements. This parameter-based approach enables efficient resource allocation without requiring hardware changes.
2Loss of energy
If the system dynamically manages transitions between processor core types, then power efficiency and resource allocation improve, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary processor management system that acts as a mediator between the workload requirements and the physical processor cores. This intermediary layer handles the complexity of core type transitions, workload analysis, and power optimization, shielding the rest of the system from complexity while enabling dynamic power-efficient operations. The intermediary manages transition states and coordinates core type changes based on workload characteristics.
3Measurement precision
If task schedulers lack core type awareness, then the scheduler implementation is simpler, but performance assessment becomes inaccurate
Solution Approach 1:
The task scheduler is enhanced with dynamic core type awareness, allowing it to identify and allocate tasks to appropriate core types based on their characteristics. The scheduler dynamically adjusts task placement decisions considering core type information (e.g., assigning performance-critical tasks to performance cores and background tasks to efficiency cores), thereby improving performance assessment accuracy while maintaining manageable complexity through rule-based allocation strategies.
