Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional fixed frequency and voltage tuning is used in multi-ASIC systems, then device complexity is reduced, but power efficiency and performance optimization deteriorate due to inherent silicon manufacturing variances
Solution Approach 1:
The patent divides the multi-ASIC system into individually tunable units, where each ASIC can have its own frequency and voltage settings adjusted independently based on its specific performance characteristics. This segmentation allows each ASIC to be optimized separately rather than forcing a uniform configuration across all devices.
Solution Approach 2:
The patent implements dynamic frequency and voltage tuning capabilities that allow the system to adaptively adjust operating parameters in real-time or near-real-time. This dynamic approach enables the system to respond to manufacturing variances and optimize power efficiency without requiring complete system redesign.
2Use of energy by moving object
If adaptive frequency and voltage tuning is implemented for each ASIC, then power efficiency improves by 5-10%, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements self-service mechanisms where each ASIC includes built-in sensors and control logic that automatically monitor and adjust its own operating parameters. This self-service capability reduces the need for external tuning equipment and simplifies the manufacturing process while maintaining optimization benefits.
Solution Approach 2:
The patent incorporates feedback loops that continuously monitor ASIC performance metrics such as power consumption, temperature, and computational throughput. This feedback information is used to automatically adjust frequency and voltage settings, creating a closed-loop system that optimizes power efficiency without requiring manual intervention or complex manufacturing processes.
3Productivity
If uniform frequency and voltage settings are applied to all ASICs, then device complexity is minimized, but performance consistency deteriorates due to silicon manufacturing variances
Solution Approach 1:
The patent applies local quality by allowing each ASIC to have customized frequency and voltage settings tailored to its specific performance characteristics. This localized tuning approach ensures that each device operates at its optimal point rather than being constrained by uniform system-wide settings, thereby improving overall performance consistency.
Solution Approach 2:
The patent utilizes parameter changes by systematically varying frequency and voltage parameters across different ASIC units based on their measured performance characteristics. This parameter optimization process enables the system to achieve consistent productivity levels across multiple devices despite inherent manufacturing variations.
4Use of energy by moving object
If individual ASIC tuning is implemented, then power efficiency improves, but system complexity and difficulty of operation increase
Solution Approach 1:
Each ASIC is equipped with self-service capabilities including built-in sensors, control logic, and automatic adjustment mechanisms that enable the device to tune its own operating parameters without external intervention. This self-service approach maintains power efficiency benefits while significantly reducing operational complexity.
Solution Approach 2:
The patent implements feedback mechanisms that automatically monitor and adjust ASIC operating parameters based on real-time performance data. This automated feedback control eliminates the need for manual tuning operations while maintaining optimal power efficiency, thereby improving ease of operation.
