1Use of energy by moving object
If standard CPU performance prediction algorithms are used to dynamically adjust CPU performance, then power consumption can be reduced, but latency increases making them unsuitable for real-time requirements
Solution Approach 1:
The patent pre-calculates and stores CPU performance profiles for different communication connection states before runtime. When the CPU needs to adjust performance, it simply retrieves the pre-determined profile corresponding to the current connection state, avoiding the latency of real-time prediction algorithms while still achieving dynamic power optimization.
Solution Approach 2:
The patent creates a dynamic CPU performance adjustment mechanism that adapts CPU resources to varying communication connection states. By linking CPU performance profiles to different connection states (e.g., idle, active, high-data-rate), the system dynamically optimizes power consumption while meeting real-time processing requirements through state-based rather than prediction-based adjustment.
2Duration of action of moving object
If CPU performance is reduced to minimize power consumption, then battery life is extended, but the functionality and processing capability of the communication device is limited
Solution Approach 1:
The patent implements dynamic CPU performance scaling that adjusts processing capability according to actual communication needs. When the communication connection state indicates low activity, CPU performance is reduced to extend battery life. When high-performance tasks are detected or connection demands increase, the system automatically retrieves higher-performance profiles, ensuring full functionality is available when needed while optimizing power consumption during normal operation.
Solution Approach 2:
The patent changes CPU performance parameters (frequency, voltage) based on communication connection state parameters. By monitoring connection state metrics and mapping them to appropriate CPU performance profiles, the system automatically adjusts processing power to match actual workload requirements, extending battery life during low-demand periods while maintaining full functionality when communication tasks require higher performance.
