Abstract
A wearable device and a power saving method are proposed. The wearable device includes a sensor and a first processing unit. The sensor has a buffer. The first processing unit is coupled to the sensor. The first processing unit in a first hibernate mode is woken up after receiving a first signal, wherein the first processing unit includes an interrupting module. The interrupting module makes the first processing unit enter the first hibernate mode after commands, in response to the first signal, the sensor to start sensing so as to generate sense data, wherein the sensor wakes up the first processing unit from the first hibernate mode based on an amount of the sense data exceeding a threshold of the buffer, and the first processing unit enters the first hibernate mode after processing the sense data.
