6.4.3
Power Plane Control
The processor core and graphics core power plane controls allow for customization to
implement optimal turbo within voltage regulator thermal limitations. It is possible to
use these power plane controls to protect the voltage regulator from overheating due
to extended high currents. Power limiting per plane cannot be guaranteed below 1
second and accuracy cannot be guaranteed in all usages. This function is similar to the
package level long duration window control.
6.4.4
Turbo Time Parameter
'Turbo Time Parameter' is a mathematical parameter (units in seconds) that controls
the processor turbo algorithm using an exponentially weighted moving average of
energy usage. During a maximum power turbo event of about 1.25 x TDP, the
processor could sustain Power_Limit_2 for up to approximately 1.5 the Turbo Time
Parameter. If the power value is changed during runtime, it may take a period of time
(possibly up to approximately 3 to 5 times the ‘Turbo Time Parameter’, depending on
the magnitude of the change and other factors) for the algorithm to settle at the new
control limits.
