Engineering Contradiction Analysis
1Reliability
If overall voltage is adjusted by hardware or power amplifiers, then voltage stability is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the voltage adjustment control into two independent modules: a first voltage adjustment module for the first processor and a second voltage adjustment module for the second processor. Each module independently adjusts voltage based on its own workload, avoiding the need for complex hardware circuits while achieving stable voltage control for each processor core separately.
Solution Approach 2:
The patent replaces traditional hardware-based voltage adjustment circuits with a software-based voltage adjustment method. The system uses workload detection algorithms and control software to dynamically adjust processor voltages, eliminating complex mechanical/electrical hardware components while achieving the same voltage stability effect.
2Reliability
If overall voltage is adjusted by hardware or power amplifiers, then voltage stability is improved, but power consumption increases
Solution Approach 1:
The patent implements local voltage adjustment for each processor based on its specific workload requirements. The first processor receives voltage adjustment based on its workload, and the second processor receives independent voltage adjustment based on its workload. This localized approach ensures each processor consumes only the necessary power for its current task, avoiding the excessive power consumption that would result from adjusting overall system voltage.
Solution Approach 2:
The patent implements dynamic voltage adjustment where the voltage for each processor is continuously adapted based on real-time workload detection. The system monitors workload changes and adjusts voltage dynamically, ensuring power consumption matches actual processing needs rather than maintaining a fixed high voltage for all processors at all times.
3Use of energy by moving object
If voltage is adjusted based on workload, then power consumption is reduced, but voltage stability may deteriorate
Solution Approach 1:
The patent implements feedback control mechanisms where the system continuously detects workload changes and adjusts voltage accordingly. The workload detection module monitors processor workload, and based on the detected workload level, the voltage adjustment modules dynamically modify voltage output. This closed-loop feedback ensures voltage stability is maintained while adapting power consumption to actual processing needs.
Solution Approach 2:
The patent changes voltage parameters dynamically based on workload parameters. When workload increases, voltage is increased to maintain stability; when workload decreases, voltage is reduced to save power. The system monitors workload intensity and adjusts voltage magnitude accordingly, ensuring both power efficiency and voltage stability through parameter adaptation.
