13. 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 reconnect
! S3 standby doesn’t allow background tasks
! Connected Standby … S0a & S0i3
! Enables comms to be “always on” during low power state
14

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
15

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
