POWER DISSIPATION
Total power dissipation has two components: one due to inter-
nal circuitry (P

See the ADSP-BF561 Blackfin Processor Hardware Reference
Manual for definitions of the various operating modes and for
instructions on how to minimize system power.
Many operating conditions can affect power dissipation. System
designers should refer to EE-293: Estimating Power for ADSP-
BF561 Blackfin Processors on the Analog Devices website
(www.analog.com)—use site search on “EE-293.” This docu-
ment provides detailed information for optimizing your design
for lowest power.
