Datasheet

Low Power Features

consumption allows for leakage current reduction, which results in platform power

savings and extended battery life. There is no platform-level change required to

support this feature as long as the VR vendor supports the VID-x feature.

2.6

Processor Power Status Indicator (PSI-2) Signal

The processor incorporates the PSI# signal that is asserted when the processor is in a

reduced power consumption state. PSI# can be used to improve intermediate and light

load efficiency of the voltage regulator, resulting in platform power savings and

extended battery life. The algorithm that the processor uses for determining when to

assert PSI# is different from the algorithm used in previous mobile processors. PSI-2

functionality improves overall voltage regulator efficiency over a wide power range

based on the C-state and P-state of the two cores. The combined C-state and P-state of

both cores are used to dynamically predict processor power. PSI-2 functionality is

expanded further to support three processor states:

• Both cores are in idle state

• Only one core is in active state

• Both cores are in active state
