P R E L I M I N A R Y
The payload power consumption was measured using the following processor:
•
Intel® Core™2 Duo processor L7400 (LV), 1.5 GHz, 667 MHz FSB, 4 MB L2 cache
with the following operating systems and test software:
•
DOS
With this operating system only one processor core was active. This operating system
has no power management support and provides a very simple method to verify the mea-
sured power consumption values.
•
Linux, IDLE Mode
With these operating systems both processor cores were in IDLE state.
•
Linux, Intel® Thermal Analysis Tool (TAT) at 75% (real application)
The power consumption values measured using the Intel® Thermal Analysis Tool oper-
ating at 75% correspond to 100% CPU usage of both processor cores and are equivalent
to the values of a maximum user application environment.
If the Intel® Thermal Analysis Tool (TAT) is operated at 75%, the power dissipated by the
processor corresponds to the maximum Thermal Design Power (TDP) as specified in the
respective datasheet for the Intel® Core™2 Duo processor.
•
Linux, Intel® Thermal Analysis Tool (TAT) at 100% (no real application)
The power consumption values measured using the Intel® Thermal Analysis Tool oper-
ating at 100% do not represent the power consumption of a real application. However,
the processor may also generate short power load pulses during normal operation. For
this reason, the power supplies must be able to deliver the amount of power required by
the AM4011 as indicated in the table below.
