System designers should refer to
Estimating Power for the
ADSP-BF531/BF532/BF533 Blackfin Processors (EE-229),
which
provides detailed information for optimizing designs for lowest
power. All topics discussed in this section are described in detail
in EE-229. Total power dissipation has two components:
1. Static, including leakage current
2. Dynamic, due to transistor switching characteristics
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
cessor activity.

DDINT
specifies the total power specification for the listed test condi-
tions, including the dynamic component as a function of voltage
(V

The dynamic component is also subject to an Activity Scaling
Factor (ASF) which represents application code running on the
processor (Table
