AMD PowerNow! Technology Dynamically Manages Power and Performance
Preliminary Information
Questions and Answers
Question:
What AMD embedded processors support
AMD PowerNow! technology
Answer:
All of the AMD-K6-2E+ and AMD-K6-IIIE+ low-power
processors are equipped with support for AMD PowerNow!
technology. AMD PowerNow! technology is not limited to any
specific speed grade, package type, or core voltage.
Question:
Is AMD PowerNow! technology backward-compatible
with older AMD x86 based embedded processors
Answer:
No. AMD PowerNow! technology is only available on
AMD’s latest low-power offerings of the embedded family of
AMD-K6 microprocessors, which consist of the AMD-K6-2E+
and AMD-K6-IIIE+ 32-bit processors.
Question:
What’s the lowest core voltage and frequency
supported
Answer:
Currently, processors equipped with AMD PowerNow!
technology can support a minimum core voltage at or above
1.4 V and operating frequencies as low as 200 MHz. Frequencies
at or above 350 MHz require a core voltage above this minimum.
AMD PowerNow! technology software is enabled with VID
codes for core voltages as low as 0.925 V.
Question:
What is “Automatic mode”
Answer:
Automatic mode is an automated mode under software
control that is supported by AMD PowerNow! technology.
Automatic mode allows for dynamic and immediate changes to
be made to the processor's operating core voltage and
frequency based on current application performance or power
requirements. The marriage of power and performance is
handled automatically through software control and operates
free of any user intervention.
Question:
How much power is saved by using the
AMD PowerNow! technology
Answer:
In embedded application testing and benchmarking,
AMD PowerNow! technology can cut power consumption from
