Total Power Dissipation
Total power dissipation has two components:
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
cessor activity.
current dissipation for internal circuitry (V
specifies static power dissipation as a function of voltage
(V
specifies the total power specification for the listed test condi-
tions, including the dynamic component as a function of voltage
(V
There are two parts to the dynamic component. The first part is
due to transistor switching in the core clock (CCLK) domain.
This part is subject to an Activity Scaling Factor (ASF) which
represents application code running on the processor core and
L1/L2 memories
