Abstract-- Diminishing voltage margins, coupled with power
and temperature constraints, call for microarchitecture-level
runtime mechanisms for voltage control. This paper describes
a localized approach for dynamic voltage management within
the domains of a Globally Asynchronous, Locally Synchronous
(GALS) processor design. Dynamic Voltage Scaling at this fine
grain level permits effective temperature management with less
performance impact than global voltage control.
