Voltage Regulator Constraints
For some platform, the voltage regulator for the shared VCC voltage rail has some 
maximum current limits. A typical voltage regulator for a platform using the SoC has a 
Thermal Design Current (I
TDC
) specification and a Maximum Current (ICC
MAX
) limit.
I
TDC
 represents the current which is sustained indefinitely by the voltage regulator (i.e., 
able to sustain a TDP workload on all processors running at warranted frequency), 
whereas the ICC
MAX
 is the peak current which the voltage regulator does source 
without tripping any protective circuitry. Any current greater than I
TDC
 is only sustained 
for a short duration, with ICC
MAX
 only sustained typically for around 10 ms.
Such voltage-regulator specifications must be taken into account when configuring the 
aggressiveness of turbo operation for the device. Turbo operating points are limited 
based on the number of active cores to keep the current drawn within the ICC
MAX
 limit.
Refer to the Edisonville/Rangeley Platform Design Guide (PDG) for additional details 
and design guidance.
9.11.1.2
Thermal Design Power Constraints
The Thermal Design Power (TDP) represents the power consumed by the device when 
running a realistic worst-case workload at T
J-MAX
 temperature. The realistic-worst-case 
workload is determined based on knowledge of the target application and realistic 
usage scenarios. The system thermal solution must be designed to dissipate the heat 
generated during a sustained period of activity with all cores running at TDP at 
guaranteed maximum frequency.

Specifications and Design Guidelines for additional details and design guidance.
