AI Technical Summary

Technical Problem

In the existing technology, the power management strategy of the duty platform processor cannot achieve a balance between ensuring the timeliness of event response and energy saving. Especially in the complex and ever-changing duty environment, the existing strategy lacks the ability to deeply learn and predict event patterns, making it difficult to balance the accuracy of energy consumption control and the timeliness of event processing.

Method used

An event-aware module continuously monitors environmental events, and a time-deterministic power management module allocates a time-deterministic execution window for each triggered event. By combining historical data, wake-up and shutdown time offsets are dynamically calculated to establish a differentiated identification and prediction model for periodic and random events. Finally, an event stream shaping module balances the processor load to achieve precise binding between the processor power consumption state and the event execution window.

Benefits of technology

It achieves the best balance between processor power consumption and response performance in complex duty environments, reduces invalid running time, improves the system's adaptability and stability under non-uniform event flow, and extends the duty platform's endurance.

Abstract

This invention relates to the field of embedded systems technology, specifically a low-power processor system for a duty platform. The system includes an event-aware module and a time-deterministic power management module. The event-aware module continuously monitors environmental event signal streams and identifies triggering events. The time-deterministic power management module allocates a time-determined execution window to each triggering event and precisely binds the processor core's power consumption state to this window in the time dimension. Specifically, it is configured to dynamically calculate the time offset based on historical event processing data, thereby waking up the processor before the expected event arrives and delaying the processor's shutdown after event processing. Through this design, the invention achieves reduced overall power consumption of the processor system while ensuring timely event processing.
