Speed and voltage selection for GALS systems based on voltage/frequency islands
Due to increasing clock speeds and shrinking technologies, distributing a single global clock signal throughout a chip is becoming a difficult and challenging proposition. In this...

Hardware based frequency/voltage control of voltage frequency island systems
The ability to do fine grain power management via local voltage selection has shown much promise via the use of Voltage/ Frequency Islands (VFIs). VFI-based designs combine the a...

Distributed DVFS using rationally-related frequencies and discrete voltage levels
Abstract--As a replacement for the fast-fading GloballySynchronous model, we have defined a flexible design style called GRLS, for Globally-Ratiochronous, Locally-Synchronous, whic...
