Total Power Dissipation
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. Electrical Characteristics on Page 18 shows the
current dissipation for internal circuitry (VDDINT). IDDDEEPSLEEP
specifies static power dissipation as a function of voltage
total power specification for the listed test conditions, including
the dynamic component as a function of voltage (VDDINT) and
frequency (Table 13).
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 memories (Table 11).
The ASF is combined with the CCLK frequency and VDDINT
dependent data in Table 13 to calculate this part. The second
part is due to transistor switching in the system clock (SCLK)
domain, which is included in the IDDINT specification equation.

(EE-297). The power vector information also applies to the ADSP-BF592
processor.
