Abstract: A processing system includes one or more sensors configured to generate sensor data while a memory of the processing system is in a low-power state. As the sensors generate the sensor data, the sensor data is stored in a buffer. The processing system further includes a sensor data management circuitry that tracks a usage of the buffer. Based on the usage of the buffer exceeding a threshold, the sensor data management circuitry is configured to wake at least a portion of the memory from the low-power state. Once the memory exits the low-power state, the processing system transfers the sensor data from the buffer to one or more locations within the memory. After writing the sensor data to the memory, the processing system then places at least a portion of the memory back in the low-power state.
