Dynamic Power Allocation Mechanism for Integrated Circuit Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional static power-sharing mechanisms fail to efficiently prioritize power budgets for integrated circuits like CPUs and GPUs under varying load conditions, leading to undesirable latencies and software execution burdens.
Innovation Solution
Implementing dynamic power allocation mechanisms where one component acts as a master controller, adjusting its power consumption to prioritize the other component based on settings in memory, allowing components to manage power sharing independently without inter-component signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized power management mechanisms are used to prioritize power consumption, then power allocation control is improved, but signal exchange latency and software execution burden increase
Solution Approach 1:
The patent divides the power management system into independent segments: each integrated circuit (CPU, GPU, etc.) has its own power management controller that independently monitors and adjusts power consumption. This eliminates the need for centralized control and inter-component signaling, thereby reducing latency while maintaining effective power allocation control.
Solution Approach 2:
Each integrated circuit is equipped with autonomous power management capabilities, allowing components to self-regulate their power consumption based on local conditions without requiring external control signals or software intervention. This self-service approach eliminates signal exchange latency while maintaining effective power prioritization.
2Device complexity
If static power-sharing mechanisms are used, then power distribution is simplified, but adaptability to varying load conditions deteriorates
Solution Approach 1:
The patent implements dynamic power management where each integrated circuit continuously monitors its power consumption and workload conditions, automatically adjusting its power usage in real-time based on current system demands. This dynamic approach maintains simple local control mechanisms while achieving high adaptability to varying load conditions.
Solution Approach 2:
Each power management controller incorporates feedback mechanisms that monitor local power consumption and workload conditions, using this information to automatically adjust power allocation decisions. This feedback-driven approach enables adaptability to changing conditions while maintaining relatively simple distributed control architecture.
3Ease of operation
If inter-component signaling is implemented for power management, then coordinated power control is improved, but overhead and latency increase
Solution Approach 1:
The patent combines power management functionality directly into each integrated circuit's local controller, merging the functions of power monitoring, decision-making, and execution into a single autonomous unit. This eliminates the need for separate signaling mechanisms and software coordination layers, reducing both overhead and latency while maintaining effective coordinated control through independent local decisions.

AI summary
Systems including a power supply and multiple chips or die, wherein settings may be configured that when applied to a first one of the chips or die configure the first chip or die to associate a power allocation limit with at least a second one of the chips or die, wherein a sum of the power allocation limit and a power consumption limit of the first chip or die exceeds a total power capacity of the power supply. The systems operate the first chip or die at a lower priority than the other chips or die for receiving operating power from the power supply, and the first chip or die is operated as a master controller of allocation of the operating power from the power supply to the first chip or die and to the other chips or die.
