See the ADSP-BF533 Blackfin Processor Hardware Reference Manual for definitions of sleep, deep sleep, and hibernate operating modes.
See Table 16 for the list of I DDINT power vectors covered by various Activity Scaling Factors (ASF).
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-
current dissipation for internal circuitry (V DDINT ). I DDDEEPSLEEP
specifies static power dissipation as a function of voltage
(V DDINT ) and temperature (see Table 14 or Table 15 ), and I DDINT
specifies the total power specification for the listed test condi-
tions, including the dynamic component as a function of voltage
(V DDINT ) and frequency ( Table 17 ).
The dynamic component is also subject to an Activity Scaling
Factor (ASF) which represents application code running on the
processor ( Table 16 ).
