Engineering Contradiction Analysis
1Productivity
If uniform frequency is supplied to all operational chips and cores, then device complexity is reduced, but computing performance is not maximized due to performance variations among chips and cores
Solution Approach 1:
The patent applies local quality by assigning different working frequencies to different operational chips and cores based on their individual performance characteristics. Each core is evaluated and assigned a specific frequency from a preset frequency set, allowing high-performance cores to operate at higher frequencies while lower-performance cores operate at appropriate lower frequencies, thereby maximizing overall computing performance without uniformly increasing complexity across the entire system.
Solution Approach 2:
The patent implements dynamics by introducing a frequency modulation mechanism that can dynamically adjust the working frequencies of operational chips and cores. The system includes a frequency modulation module that receives performance evaluation results and automatically adjusts frequencies in real-time, transforming the static uniform frequency assignment into a dynamic adaptive frequency distribution system that responds to actual performance variations.
2Productivity
If frequency modulation is applied to each core based on performance, then computing performance is maximized, but device complexity increases due to additional modulation mechanisms
Solution Approach 1:
The patent applies self-service by designing a system where the frequency modulation module automatically evaluates core performance and adjusts frequencies without requiring external intervention. The system includes built-in performance evaluation capabilities and automatic frequency assignment mechanisms that operate autonomously, reducing the need for complex external control systems while maximizing operational performance through adaptive frequency management.
Solution Approach 2:
The patent implements feedback by creating a closed-loop system where core performance is continuously evaluated and the results are fed back to the frequency modulation module. This feedback mechanism allows the system to automatically adjust frequencies based on actual performance measurements, ensuring optimal operational performance while keeping the modulation mechanism manageable through intelligent control rather than brute-force complexity.
3Speed
If higher frequencies are assigned to all chips, then computing speed increases, but energy consumption increases and lower-performance chips are overloaded
Solution Approach 1:
The patent applies parameter changes by systematically varying the working frequency parameter across different operational chips and cores based on their performance capabilities. Instead of using a single high frequency for all components, the system implements a distributed frequency spectrum where each chip operates at an optimized frequency level, achieving high computing speed for capable components while conserving energy for lower-performance components that would be overloaded by high frequencies.
