Dyanamically adapting a voltage of a clock generation circuit

摘要

In one embodiment, a processor includes a plurality of functional units each to independently execute instructions and a clock distribution circuit having a clock signal generator to generate a clock signal. The clock distribution circuit is coupled to receive a first operating voltage from a first voltage rail and the functional units are coupled to independently receive at least one second operating voltage from one or more second voltage rails. Other embodiments are described and claimed.
