1Use of energy by moving object
If existing VRM architectures are used to regulate voltage, then voltage regulation function is provided, but power efficiency is insufficient and response speed is slow
Solution Approach 1:
The VRM system implements dynamic voltage adjustment capabilities that allow real-time optimization of power delivery based on actual component needs. The system continuously monitors power consumption and dynamically changes voltage levels, enabling faster response to load changes while improving overall power efficiency compared to static VRM architectures.
Solution Approach 2:
The system incorporates feedback mechanisms where power consumption is monitored and used to adjust voltage output. This closed-loop control enables the VRM to respond quickly to changing conditions and optimize power delivery in real-time, simultaneously improving power efficiency and response speed.
2Use of energy by moving object
If voltage regulation is adjusted based on multiple dependencies (time, application, data, user), then power optimization is improved, but system complexity increases
Solution Approach 1:
The VRM system is designed to handle multiple types of dependencies (time, application, data, user behavior) through a unified control architecture. This multi-functional approach allows the system to optimize power delivery across various scenarios without requiring separate specialized systems for each dependency type, balancing power optimization with manageable complexity.
Solution Approach 2:
The system incorporates autonomous decision-making capabilities that allow it to automatically adjust voltage based on monitored conditions without requiring constant external intervention. This self-service approach simplifies the overall system architecture by embedding intelligence within the VRM itself, reducing the need for complex external control mechanisms.
3Use of energy by moving object
If power monitoring and control is implemented for multiple components, then power efficiency is optimized, but communication infrastructure complexity increases
Solution Approach 1:
The system consolidates power monitoring and control functions for multiple components into a unified VRM architecture. By merging these functions, the system achieves comprehensive power optimization across multiple components while using a single communication interface (PMBus), thereby reducing overall communication infrastructure complexity compared to having separate control systems for each component.

AI summary
Systems and methods for improving power efficiency of electronic systems are disclosed. An intelligent voltage regulator module (VRM) can self-regulate the output power provided to one or more components of an electronic system. For example, output voltage to a component can be increased when more computational power is needed or lowered when appropriate. The intelligent VRM can regulate the output power, for instance, based on one or more of usage or activity of the component. In some cases, the intelligent VRM can independently regulate the output power without input from a host device or override one or more output power parameters. Adjustment of the output power can be performed using machine learning (ML).
