Page 22 of this presentation describes the "Dynamic Frequency Adjustment". "Dynamic Frequency Adjustment" means that processor clock cycles not only can be measured (with the proper equipment), but they can be individually controlled (shunken or stretched) for specific cycle(s) on certain processor implementations.

Clocking control is just one of the design for testability features that is built into various modern micro's. Very useful for validating the existence of suspected speedpaths.
