Power throttling system for managing device power consumption
A recently granted patent (Publication Number: US11927932B2) discloses a system designed to manage power consumption in devices efficiently. The system includes a power profile engine that receives a desired power profile for a device, with specific current averages associated with different time durations. A power throttling signal generator is then utilized to throttle power consumption in response to measured currents exceeding the specified profile averages. The system allows for user programmable power profiles and employs components like resistors, analog to digital converters, accumulators, and FIFO registers to facilitate power management effectively.
Furthermore, the patent details a method for implementing the power management system, emphasizing the generation of power throttling signals based on running averages of measured currents compared to the desired profile averages. The method includes steps for converting measured currents to digital format, determining throttling values for power reduction, and adjusting power consumption based on the generated signals. Additionally, the system is specifically designed for machine learning application-specific integrated circuits (ASICs) and includes features for tracking performance throttling instances and maximum current values triggering power throttling signals. Overall, the patent highlights a comprehensive approach to power management in devices, ensuring efficient utilization and optimization of power resources for enhanced performance and longevity.
