LIMITS MANAGEMENT FOR A PROCESSOR POWER DISTRIBUTION NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17941535 titled 'LIMITS MANAGEMENT FOR A PROCESSOR POWER DISTRIBUTION NETWORK
Simplified Explanation
The patent application describes a system for managing limits on processor power distribution networks.
- Electronic device with a processor and processing core coupled to an external power rail.
- Current sensor produces current sensor readings associated with the power rail output.
- State-space unit applies current sensor readings to a predictive model to predict a current budget for the processing core.
- Limit manager generates a current limit based on the current budget to limit current draw of the processing core.

Original Abstract Submitted
Aspects relate to limits management for a processor power distribution network. In an aspect, an electronic device has a processor with a processing core that is coupled to a power rail. The power rail is external to the processor. A current sensor is associated with the output of the power rail and configured to produce current sensor readings. A state-space unit is coupled to the current sensor. The state-space unit has a predictive model to apply the current sensor readings to the predictive model to predict a current budget for the processing core. A limit manager is configured to generate a current limit in response to the current budget. The limit manager limits a current draw of the processing core in response to the current limit.
