A method for timestamping and synchronization with high-accuracy timestamps in low-power sensor systems is provided. The method is performed by a device and includes: receiving, by a sensor hub of the device, an interrupt signal from a sensor and performing an interrupt service routine (ISR) to obtain an interrupt timestamp obtained by a latch, wherein the interrupt timestamp is obtained from an always-running unified time reference; obtaining, by the sensor hub, sensor data from the sensor; predicting, by the sensor hub, a prediction timestamp based on an amount of sensor data and the interrupt timestamp by using a filtering algorithm; and correcting, by the sensor hub, a timestamp of each sensor data based on the prediction timestamp.

A memory management system includes a memory, a processor, a memory access monitoring module and a memory management module. The processor is used to access the memory. The memory access monitoring module includes a first terminal coupled to the processor, and a second terminal coupled to the memory. The memory access monitoring module is used to monitor whether the processor has accessed the memory so as to generate monitor data. The memory management module is used to receive the monitor data and predict when the memory is to be accessed according to at least the monitor data.
