Engineering Contradiction Analysis
1Measurement precision
If conventional computer models are used to estimate power consumption, then measurement precision is improved, but device complexity and use of energy increase
Solution Approach 1:
The chipset is divided into multiple functional blocks (e.g., baseband processor, RF processor, memory interface, I/O interface), each with its own power consumption characteristics. This segmentation allows the complex power estimation problem to be broken down into manageable components, reducing overall system complexity while maintaining estimation accuracy.
Solution Approach 2:
The patent transforms the complex computer model into a simplified mathematical model using power consumption equations with key parameters such as operational mode indicators, data throughput rates, and functional block activation states. This parameter-based approach maintains measurement precision while dramatically reducing computational complexity and energy requirements.
2Measurement precision
If conventional computer models are used to estimate power consumption, then measurement precision is improved, but use of energy increases
Solution Approach 1:
Instead of running complex computer models that consume significant energy, the patent creates simplified power consumption equations that copy the essential behavior patterns of the full model. These equations use predetermined coefficients and key operational parameters to reproduce power estimation results with acceptable accuracy while consuming minimal energy.
Solution Approach 2:
The estimation approach changes from using comprehensive detailed parameters in complex models to using a select few key parameters (operational mode, data rate, active functional blocks) in simplified equations. This parameter reduction maintains sufficient measurement precision for power management decisions while dramatically reducing the energy required to perform estimations.
3Productivity
If real-time power consumption estimates are performed using conventional methods, then productivity is improved, but use of energy increases
Solution Approach 1:
The patent implements dynamic power estimation that adapts to changing operational conditions in real-time. The system continuously monitors operational modes, data throughput, and functional block states, updating power consumption estimates using the simplified equations. This dynamic approach enables real-time productivity improvements for power management while keeping energy consumption low due to the computational efficiency of the equations.
