APPARATUS, SYSTEM, AND METHOD FOR PROVIDING CLOCK SIGNAL ON DEMAND

摘要

Described herein are apparatus, system, and method for providing clock signal on demand. The method comprises determining an indication of clock signal usage in multiple hardware logic units; generating an enable signal according to the indication; and gating or un-gating the clock signal for clock islands of at least a hardware logic unit, of the multiple hardware logic units, in response to a logic level of the enable signal, wherein the clock islands are part of a global clock distribution network and are operable to be enabled or disabled independently.
