Abstract
A processor prunes state information based on information provided by software, thereby reducing the amount of state information to be stored prior to the processor entering a low-power state. The software, such as an operating system or application program executing at the processor, indicates one or more registers of the processor as storing data that is no longer useful. When preparing to enter the low-power state, the processor omits the indicated registers from the state information stored to memory.
