•Intel‟s SpeedStep processor technology
Intel‟s SpeedstepTM technology based processors and their successors are capable of:
•Changing the internal clock frequencies
•Adapting core voltage to changes in power supply
•Switching of selective parts of the CPU cores / CPU on or off depending on whether the current calculations require them to be available
•Using the reduced the clock rate and voltage of the processor core while on batteries, leading to significant power saving.
•Switching between these modes is transparent to user and is usually fast <however, while the system is connected to external power supply, the full clock rate and core voltage is available to processor resulting into maximum performance>
•Transmeta‟s Crusoe processor technology
•Total number of transistors are reduced in an attempt tosave the power consumption
•Software replaces the functionalities which otherwise would have been provided in hardware by the eliminated set of transistors
•Software dynamically translates the original instructions into another set of instruction for the processor
•A technology called LongRunTM reduces the power consumption even more by reducing the processor's voltage on the fly when processor is idle
•Motorola‟s Dragon Ball processor technology
•Deprecated now!
•Intel‟s X-Scale processor technology
•This is next generation of ARM-processors that have replaced the Intel StrongARM series
