BACKGROUND CONNECTED STANDBY

TECHNOLOGY

14

WHAT IS THE NEED FOR CONNECTED STANDBY?

! Existing sleep models … Sleep S3 ! No method to maintain communication channels and device driver

operation

! Transitions in/out of S3 require comms (WWAN, WLAN, etc.) to re-connect

! S3 standby doesn’t allow background tasks

! Connected Standby … S0a & S0i3 ! Enables comms to be “always on” during low power state

15

WHAT IS CONNECTED STANDBY? ! System-wide power-idle state, based on user presence

! “Always On” –  CS systems maintain the appearance of being always on

–  Very low latency from ‘screen off’ to full-power (latency limits mandated by MS)

! “Always Connected” –  Maintains comms connections during ‘user not present’ sleep state

! Smart Phone model –  User not present … provide low-power operation

–  User present … provide high performance

–  Very fast switching between modes

! Power-idle functions –  AMD defined ‘which components are active’ in this power state … not set

by OS

16

CHARACTERISTICS OF A CONNECTED STANDBY SYSTEM

! User present - new power state: S0a [ACPI S0] !  System works like classical S0 state

!  Full performance of all devices

! User not present - new power state: S0a & S0i3 [ACPI S0] !  Always on (stays in ACPI S0)

–  Maintains comms and peripheral connections

–  Supports applications/tasks in burst method [~30 second cycles]

!  Always connected –  Stays connected to devices and comms channels

!  Instant On and Off transitions – required < 300ms < 500ms !  Between ‘user not present’ states S0i3 & S0a

!  Between ‘user not present’ and ‘user present’

!  Shutdown - S4 !  Only at critical battery level

!  CS system never reboots and never powers down
