T
LA
is the Local Ambient temperature for the Nominal thermal profile.
T
LA-ST
designates the Local Ambient temperature for Short-Term operation.
P is the processor power dissipation.
Table 5-4 provides the
PSI
PA
and T
LA
parameters that define T
DTS
thermal profile for
each TDP/Core count combination. Figure 5-4 illustrates the general form of the
resulting linear graph resulting from
T
DTS
= PSI
PA
* P + T
LA
.
The slope of a DTS profile assumes full fan speed which is not required over much of
the power range. Tcontrol is the temperature above which fans must be at maximum
speed to meet the thermal profile requirements. Tcontrol is different for each SKU and
may be slightly above or below T
DTS-Max
of the DTS nominal thermal profile for a
particular SKU. At many power levels on most embedded SKU’s, temperatures of the
nominal profile are less than Tcontrol as indicated by the blue shaded region in the DTS
profile graph of Figure 5-4. As a further simplification, operation at DTS temperatures
up to Tcontrol is permitted at all power levels. Compliance to the DTS profile is required
for any temperatures exceeding Tcontrol.
