Abstract
Techniques and tools for reducing power consumption of computing devices (e.g., mobile devices such as mobile phones and tablet computers) that perform position tracking operations are described. In described examples, a low-power processor calculates (e.g., in real time) position information (e.g., GPS position fixes) based on information received from a positioning system (e.g., GPS) and stores the position information for later use in a buffer associated with the low-power processor (e.g., in storage on the low-power processor). Described examples allow position information to be calculated in real time and stored while the device is in a low-power state, and can be used with location-based applications that do not require position information to be delivered to the application in real time.
