  • Page 82: Adaptive Battery Life Extender (Able-2) Feature

    10.5 Adaptive Battery Life Extender (ABLE-2) Feature This feature provides power saving without performance degradation. The ABLE-2 technology intelligently manages transition among power modes within the device by monitoring access patterns of the host. This feature has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode. This feature allows the host to select a power management level.
  • Page 83 Each time this algorithm decides that the current burst of commands is not yet complete, it places the device in Performance Idle mode. This means another command will arrive very soon, and the response to it can now be instantaneous without the delay associated with conventional idle. Since bursts usually contain tens of commands, performance is improved.

  • Page 84: Function

    10.6 S.M.A.R.T. Function The intent of Self-monitoring, analysis and reporting technology (S.M.A.R.T) is to protect user data and prevent unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, S.M.A.R.T devices employ sophisticated data analysis algorithms to predict the likelihood of near-term degradation or fault con- dition.

  • Page 85: Operation With Power Management Modes

    10.6.6 S.M.A.R.T. operation with power management modes It is recommended that, when a host system utilizes both the power management and S.M.A.R.T. features, the system enable the device's attribute autosave feature to allow the device's automatic attribute saving upon receipt of STANDBY IMMEDIATE or SLEEP commands. If the device has been set to utilize the standby timer, the devce also saves attributes values prior to going from an Idle state to Standby state.

    10.8 Protected Area Function (Vendor Specific) Protected Area Function is to provide the 'protected area' which can not be accessed via conventional method. This 'protected area' is used to contain critical system data such as BIOS or system management information. The contents of entire system main memory may also be dumped into 'protected area' to resume after system power off.

When the sector of data is available for transfer to the host, the device sets B S Y = 0 , sets D R Q = 1 , and interrupts the host.
