Societal Demands
►Regular
customers are demanding energy efficiency in all their
products, either in the production process or in the day-to-day use of
the device
►Green Guilt
You tree-killer!
• Shame on you for asking for plastic bags!
• Consider yourself absolved!

Energy Star
► http://www.energystar.gov/
► United
States effort to get a handle on energy inefficiency in several
applications
• The ENERGY STAR label was established to:
• Reduce greenhouse gas emissions and other pollutants caused by the
inefficient use of energy
• Make it easy for consumers to identify and purchase energy-efficient
products that offer savings on energy bills without sacrificing performance,
features, and comfort
► In 2009, Energy Star prevented 45 million metric tons of greenhouse gas
emissions and consumers saved nearly $17 billion on utility bills
► No
•
•
longer just refrigerators or washer/dryers
Any appliance
And now entire homes can be Energy Star certified

Energy Using Products
►http://ec.europa.eu/enterprise/policies/sustainable-
business/ecodesign/index_en.htm
►EuP energy efficiency requirements*
Enforceable since January 2009
• By 2010, the standby power consumption of equipment in any condition
has to be
•
•
less than 1 Watt if the equipment is providing a reactivation function or
2 Watts if the equipment is providing a status/information function
These values will be lowered in 2013
►Companies
will be required to collect and report upon various
energy metrics related to the energy utilization of particular product
groups

What Does it Mean to be Energy Efficient and Green?
► Power
and energy are not the same thing
Power : PTOT = ISTATICV + aCV2F
P1>P2
E1=E2
► Power:
Peak and RMS power supply requirement
► Energy: Thermal design and consumption cost
► Energy depends on nature of application
•
•
•
IO and Cache result in core and bus stalls
Operation temp influences power consumption
Degree of cyclical nature of workload vary by application
► Advanced power and energy management
• Traditional Modes: Run, Doze, Nap, Sleep
• New mode to “pace” energy use to valued work output
• Run
• JOG
• Packet-lossless Deep Sleep
• Fast recovery from transitional states
► Examples of a cyclical application
• Instrument: medical, engineering, automation, POS
• Premise router: home, SoHo, SMB
• Office Automation: storage, printers, telephones, etc.
Energy pacing to workload
Cyclic Workload
Description
Active workload
Active state: e.g. printing,
motion, routing
Light workload
System management and
services: e.g. networking
management, calibration,
web services
Dormant
Does not mean dead: e.g. quick
wake to key event, respond
to network overhead traffic
(ping, ARP, etc)
► Energy
efficiency is using less energy to provide
the same level of service

Dynamic vs. Static Power
Core power can be separated into two conceptual components
Parameter
Dynamic Power
Static Power
Cause
Transistor switching (“AC power”)
Transistor leakage current (“DC power”)
Voltage
Depends on voltage (V2 relationship)
Depends on voltage (V relationship)
Temperature (TJ)
No dependence
Increases with temperature, may double
between 65°C and 105°C for 90nm
Frequency
Linear dependence on core & platform
frequency
No dependence
Application
Very dependent on application.
Dhrystone dissipated more power than
networking applications.
No dependence
Process
Not significant
May vary from part to part, frequency bin
Measurement
Run an application (best to use one that
has same peak and average power such
as Dhrystone)
Estimation methods:
► Extrapolation down to zero hertz
► Sleep mode

Note: Extremely low energy consumption achieved by ‘postponing’ to respond to

What to Watch For When Going for Energy Efficiency
► Clock
generators
• Power only exists while switching. By definition, a clock exerts power
every half cycle
► Gigabit Ethernet PHY
• 10/100 power is 50% or less than that of 1 gig
► Power supplies
• Can be extremely inefficient if not designed carefully (85% is considered
great?!)
► DDR3 clock terminations
• Don’t let the DDR3 vendors fool you! There is more power hidden than
you realize
► 3.3V rails
• 3.3 time X amps adds up fast
► Thermals
• Keep it cool!

Clocks
►Consider
clock consolidations – less than 166 MHz should not be
an issue from a signal integrity perspective
DDRCLK tied to SYSCLK
• PCI CLK tied to SYSCLK
•
►Watch
those buffers
Some multiple input buffers still leak or run even without a need
• Turn them off in SW or with proper strapping
•

PHYs
►Can
your application use 10/100?
1 gig is becoming the norm
• Possibly the biggest source of power on the system in a low power state
and 2nd largest in a dynamic state after the processor itself
•
►Don’t
forget the transmitters too
In deep sleep the link must stay active
• Need low power PHYs to accommodate
•

Power Supplies
►Designing
a power supply that can perform well, deliver at peak
power, AND be efficient during low power modes is challenging
►Efficiency
generally goes down when drawing low power
►Upwards
of 95% efficiency can be realized with some research and
simulation

Termination
►While
DDR3 devices can achieve very low power in self-refresh
mode, there is no way to disable the clock termination during these
modes
►With standard termination, this can consume almost 200 mW
►Through careful simulation, increasing the value of the termination
can achieve closer to 80 mW
►There may be other termination schemes (such as LVDS-like
termination) that may improve the power slightly

High Voltage Rails
►Freescale
•
devices require OVdd at 3.3V
Runs much of the I/O on the device
►Consider
the 2.5V rail where appropriate
►Minimize the power on that rail during deep sleep
•
Delete the IO that is not necessary to the final product (BOM-optimize
for power, not just cost)
