AMD-K6™-IIIE+ Embedded Processor Data Sheet
AMD PowerNow!™ Technology for Enhanced Power Management
AMD has added a number of new power management features to the low-power
versions of the AMD-K6-IIIE+ processor. Collectively, these hardware and software
features are called AMD PowerNow!™ technology.
AMD PowerNow! technology allows the AMD-K6-IIIE+ processor to run at different
frequencies and voltages, depending on the application’s need for maximum
performance or the most efficient power utilization.
AMD PowerNow! technology includes AMD’s unique “automatic mode” feature, which
allows the system to monitor application usage and to continuously vary the operating
frequency and voltage, delivering performance on demand while dissipating the
lowest amount of power possible.
AMD PowerNow! technology enables embedded products to dynamically manage
power and performance.
System Management Mode and Other Power Management Features
The AMD-K6-IIIE+ processor includes the complete industry-standard system
management mode (SMM), which is critical to system resource and power
management.
The AMD-K6-IIIE+ processor also features the industry-standard Stop-Clock
(STPCLK#) control circuitry and the Halt instruc tion, both required for
implementing the ACPI power management specification.
Microarchitecture
The AMD-K6-IIIE+ processor’s 6-issue RISC86 microarchitecture is a decoupled
decode/execution superscalar design that implements state-of-the-art design
techniques to achieve leading-edge performance.
Advanced design techniques implemented in the AMD-K6-IIIE+ processor include
multiple x86 instruction decode, single-clock internal RISC operations, ten execution
units that support superscalar operation, out-of-order execution, data forwarding,
speculative execution, and register renaming.
6
When application demands require the processor to run at maximum
performance, the AMD PowerNow! technology steps up the performance to meet
the demand.
As platform demand for performance subsides, AMD PowerNow! technology can
dynamically drop into a lower power state.
