Sensor Processor Batching for Mobile Battery Conservation

The patent divides the processing system into two separate components: a main application processor and a sensor processor. The sensor processor is a dedicated low-power component that continuously acquires sensor data and stores it in a circular buffer, while the main application processor remains inactive or in low-power mode. This segmentation allows sensor data collection to continue without keeping the power-intensive main processor active, thus resolving the contradiction between data availability and power consumption.

The sensor processor is designed as a self-service component that autonomously acquires sensor data, stores it in the circular buffer, and manages its own operation without requiring the main application processor to be active. Applications can retrieve data from the circular buffer when needed, and the main processor only activates briefly for data retrieval and processing rather than continuous operation, significantly reducing overall power consumption while maintaining productivity.

The system implements periodic action by having the sensor processor acquire sensor data at continuous intervals and store it in the circular buffer, while the main application processor activates periodically only when applications need data. This allows the sensor data to be continuously collected and kept fresh in the buffer, while the main processor consumes power only periodically when data retrieval is necessary, resolving the contradiction between data freshness and energy loss.
