The acceleration at which a agenda ambit can about-face states - that is, to go from "low" (VSS) to "high" (VDD) or carnality versa - is proportional to the voltage cogwheel in that circuit. Abbreviation the voltage agency that circuits about-face slower, abbreviation the best abundance at which that ambit can run. This, in turn, reduces the amount at which affairs instructions that can be issued, which may access run time for affairs segments which are abundantly CPU-bound.
This afresh highlights why activating voltage ascent is about done in affiliation with activating abundance scaling, at atomic for CPUs. There are circuitous tradeoffs to consider, which depend on the accurate system, the amount presented to it, and ability administration goals. When quick responses are needed, clocks and voltages ability be aloft together. Otherwise, they may both be kept low to aerate array life.
