Processor-Integrated Offset Voltage for Fast Transient Regulation

The patent merges the voltage regulation control function directly into the processor by integrating the offset voltage generation circuitry. This eliminates the need for separate bus connections between the processor and voltage regulating member, as the processor can now directly provide the offset voltage to the voltage regulating member through integrated circuits, thereby reducing circuit board complexity while maintaining voltage regulation functionality.

The patent introduces an offset voltage as an intermediary parameter that bridges the processor and voltage regulating member. Instead of requiring complex bus communication protocols, the processor generates an offset voltage that directly represents the desired core voltage adjustment, which is then applied by the voltage regulating member. This intermediary approach simplifies the interaction interface and reduces communication overhead.

The patent extracts the offset voltage generation function from the external voltage regulating member and relocates it directly into the processor. This extraction eliminates the need for bus communication delays in the feedback loop, as the processor can immediately generate and apply offset voltage adjustments based on its internal voltage predictions, significantly reducing closed-loop regulation time and improving transient performance.

The patent implements preliminary action by having the processor predict the required core voltage in advance based on current load conditions and generate the corresponding offset voltage before it is actually needed. This proactive approach allows the voltage regulating member to receive pre-calculated voltage adjustment commands, eliminating waiting time in the closed-loop regulation process and improving transient response.
