Engineering Contradiction Analysis
1Productivity
If multiple processors are used to increase processing power, then productivity is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts processor states based on task requirements. The power management circuit transitions processors between active and sleep states, and between different performance modes, to match computational demands. This dynamic adaptation allows the system to maintain high productivity when needed while minimizing power consumption during low-demand periods.
Solution Approach 2:
The invention changes operational parameters of processors based on task characteristics. The power management circuit modifies voltage, frequency, and operational mode parameters according to the computational requirements of assigned tasks, enabling optimal balance between processing power and power consumption for each specific workload.
2Adaptability or versatility
If heterogeneous processors with different architectures are used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power management circuit acts as an intermediary that abstracts the complexity of heterogeneous processors. It provides a unified interface for task assignment and power management, automatically handling the complexities of coordinating different processor architectures, memory systems, and power domains without requiring complex external control logic.
Solution Approach 2:
The power management circuit implements universal control mechanisms that work across all processor types in the heterogeneous system. It provides standardized power management, task assignment, and state transition control that functions consistently whether managing simple or complex processors, thereby reducing overall system complexity despite architectural diversity.
