Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If peak power is set to prevent power spikes and voltage droops, then system reliability is improved, but processor performance is reduced due to frequency limitations
Solution Approach 1:
The patent implements dynamic peak power adjustment by monitoring throttling signal assertions and automatically modifying the peak power setting. The system transitions from static to dynamic power management, allowing the processor to operate at higher frequencies when conditions permit while maintaining reliability through real-time adjustments based on actual system behavior
Solution Approach 2:
The system uses feedback from throttling signal assertions to continuously refine peak power settings. By monitoring whether throttling events occur and adjusting peak power accordingly, the system creates a closed-loop control mechanism that balances reliability and performance based on actual operating conditions rather than fixed conservative limits
2Stability of the object's composition
If peak power is set too low to ensure reliability, then system stability is improved, but power management complexity increases due to frequent throttling
Solution Approach 1:
The system performs self-adjustment by automatically modifying peak power settings based on monitored throttling events. The power management circuitry autonomously learns from system behavior and adjusts parameters without external intervention, reducing the need for complex manual configuration and optimization while maintaining stability
3Productivity
If peak power is increased to improve performance, then processor frequency is improved, but system reliability deteriorates due to power spikes and voltage droops
Solution Approach 1:
The system takes preliminary action by proactively adjusting peak power settings before performance degradation or reliability issues occur. By monitoring throttling signals and preemptively modifying power limits, the system prevents extreme power spikes and voltage droops while maintaining high performance operating windows

AI summary
Peak power setting circuitry is provided to set a peak power value for an integrated circuit device. A power supply interface is to receive a value to estimate a peak power capacity of a power supply serving the integrated circuit device and processing circuitry is provided to calculate an approximate peak power for the integrated circuit device. A peak power for the integrated circuit device is determined by increasing the approximate peak power depending on an amount by which the integrated circuit device power is reduced in response to assertion of a throttling signal.
